Why sodium iodide is 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).

What occurs in the process of solvation of sodium iodide by water?

2H2O + 2Na → 2NaOH + H2 it reacts with water to form sodium hydroxide where the sodium was dissolve in water to form sodium hydroxide. Yes you don’t need to heat it or stir it. It will dissolve it selves and produce flame.

Why is sodium iodide soluble in acetone?

Iodide ion is a good nucleophile and sodium iodide is quite soluble in acetone. On the other hand, sodium chloride and sodium bromide have low solubilities in acetone. As a result, the reaction of alkyl bromides and alkyl chlorides with NaI/acetone can serve as a simple test reaction as indicated below.

Is sodium sulfate soluble in water?

WaterSodium sulfate / Soluble in

Why are salts 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. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

Why in sodium chloride is soluble in water but insoluble in acetone?

Sodium chloride is an ionic molecule. There exists electronegativity difference between Sodium and Chlorine, which gives polarity to the molecule. Thus sodium chloride is polar molecule. Generally polar molecules will soluble in polar solvents and insoluble in non-polar solvents.

Is sodium bicarbonate soluble in acetone?

Yes, acetone ignores bicarbonates, but if you dissolve sodium bicarbonate in vinegar, it’ll clean the sodium acetate crystals 🙂 More information about Sodium carbonate (Na2CO3).

Why is sodium sulphate insoluble?

Sodium is alkali metal, while Barium is alkaline earth metal, so Sodium Sulphate has higher hydration energy than Lattice energy. And Barium sulphate has higher Lattice energy than Hydration energy. Thus, sodium sulphate is soluble in water while Barium sulphate is sparingly soluble in water.
