Why is NaI more soluble than NaCl?

Since size of ions is inversely proportional to the lattice energy, Na+ and I- ions in NaI will require less energy to break away from the lattice as compared to Na+ and Cl- ions in case of NaCl. So, in one statement- NaI has better solubility due to lesser requirement of energy in order to break its lattice.

Why NaCl is soluble in water but NaI is not?

Selina – Chemistry – Class 7 Water can dissolve salt because the negative chloride ions are attracted by the positive portion of water molecules and the positive sodium ions are attracted by the negative portion of water molecules. Iodine has a very low solubility in water because it is non-polar.

Does NaI increase in solubility?

5. The solubility trend of the sodium halide salts (NaF, NaCl, NaBr, NaI) is that the solubility increases with increasing ionic radius of the halide. This means the solubility increases down the halogen group when they are bonded to sodium ions. In other words, NaI is more soluble than NaBr.

Is NaI insoluble in water?

Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na+) and iodide anions (I−) in a crystal lattice.

Why is NaI soluble?

NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).

Will sodium iodide NaI dissolve in water?

Is NaI Soluble or Insoluble in Water? – YouTube – Time: 0:001:47 – https://www.youtube.com/watch?v=XJT-jAEJAZc

Is NaI an aqueous solution?

An aqueous solution of NaI was introduced into the vacuum as a continuous liquid flow (liquid beam), and the liquid beam was irradiated with a UV laser pulse. The abundance of electrons emitted by the laser excitation was measured as a function of wavelength (photodetachment spectroscopy).

Why is NaI neutral?

The iodide anion is the extremely weak conjugate base of a strong monoprotic acid (HI), so it also has no effect on the solution pH. Therefore, this solution will have a neutral pH of 7 at a temperature of 25 degrees Celsius.

Why NaCl is water soluble but NaI is not?

Water can dissolve salt because the negative chloride ions are attracted by the positive portion of water molecules and the positive sodium ions are attracted by the negative portion of water molecules. Iodine has a very low solubility in water because it is non-polar.

Why is NaI very soluble in water?

NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).

Why is sodium bromide more soluble than sodium chloride?

Solution – Why is Sodium Bromide more soluble in water compared to Sodium Chloride? Answer -NaBr is a polar compound. Yes, it is very soluble in water. NaBr is an ionic compound.

How can you differentiate NaCl from NaI?

Sodium chloride and sodium iodide are such two compounds that are sodium halides. The main difference between sodium chloride and sodium iodide is that sodium chloride is composed of a chloride ion bonded to a sodium ion whereas sodium iodide is composed of an iodide ion bonded to a sodium ion.

Is NaI more soluble than NaCl?

This means the solubility increases down the halogen group when they are bonded to sodium ions. In other words, NaI is more soluble than NaBr. NaBr is more soluble than NaCl and NaCl is more soluble than NaF.

Why does NaI dissolve in water?

NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).

Why is NaCl so soluble in water?

Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.

Is NaI highly soluble in water?

Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine….Sodium iodide.

Is NaI insoluble or soluble?

Sodium iodide is a water-soluble ionic compound with a crystal lattice.

How soluble is NaI?

Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine….Sodium iodide.

Why is NaI so insoluble in water?

The ionic NaI is a polar molecule and therefore would dissolve in the water adding to the overall entropy of the system. You can check polarity using molecular geometry and shape to help distinguish a diploe.

Why is iodine insoluble in water?

Iodine does not dissolve in water because water is an extremely polar molecule, while iodine exists in the diatomic form of I2 , and is therefore non-polar, and will not dissolve in water.

Why is sodium so soluble in water?

At the molecular level, salt dissolves in water due to electrical charges and due to the fact that both water and salt compounds are polar, with positive and negative charges on opposite sides in the molecule.

Why sodium bromide is soluble in water?

Sodium bromide (NaBr) dissolves in water because of the hydration energy released as a result of ion-dipole interactions formed between water and sodium and bromide ions.

Why is NaCl more soluble than NaF?

NaBr is more soluble than NaCl and NaCl is more soluble than NaF. Fluorine is at the top of the halogen group and iodine is the at the bottom of the halogen group just above astatine. This means that fluorine has the smallest ionic radius of all of the halogens. Smaller ions are closer together in solution.

How can you tell the difference between NaCl and NaBr?

Method 1: identify aqueous NaCl from aqueous KCl from aqueous silver nitrate. With silver nitrate, NaCl and NaBr gives AgCl and AgBr precipitates respectively.AgCl is not soluble in water and form a white color precipitate.AgBr is a pale yellow color insoluble precipitate in water.

How do you identify sodium chloride?

Sodium chloride contains 39.3% sodium and 60.7% chloride by weight, as determined from the atomic weight of sodium (22.99 g/mol) and chlorine (35.45 g/mol). This means that when sodium chloride is dissolved in solution, there are 0.30 g (300 mg) of chloride ions and 0.19 g of sodium ions.

How do you test for NaI?

Procedure: In a small test tube (13 x 100mm), add 2mL of 15%NaI in acetone solution. 16 Add 4 drops of liquid sample or 40mg of solid dissolved in the minimal amount of ethanol. Mix the test tube by agitating. A positive result is a sustaining white cloudiness.

How would you separate iodine and sodium chloride?

Either by sublimation or by extraction with CCl4 followed by evaporation we can separate iodine from sodium chloride.

Why is sodium so soluble?

Table salt dissolves in water because the very polar water molecules attract both the positively charged sodium ions and the negatively charged chloride ions.

Is sodium highly soluble in water?

Solubility of sodium and sodium compounds At 20oC solubility is 359 g/L, in other words adequately water soluble. Solubility is nearly temperature independent. Sodium carbonate (Na2CO3) is also adequately water soluble. Solubility is 220 g/L at 20oC.

Is sodium bromide soluble in water?

Sodium bromide is an inorganic compound with the formula NaBr….Sodium bromide.

Is sodium bromide soluble or insoluble?

Sodium bromide

Does bromide dissolved in water?

Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water.

Is NaCl or NaBr more soluble in water?

This means the solubility increases down the halogen group when they are bonded to sodium ions. NaBr is more soluble than NaCl and NaCl is more soluble than NaF. Polar solvents dissolve polar compounds, and non-polar solvents dissolve non-polar molecules.
