## How do you determine solubility of salt?

Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

### Which salt has lowest solubility?

The hydration enthalpy of barium sulphate is less than that of magnesium sulphate. Because of the big size of barium metal ion, the lattice enthalpy of barium sulphate increases so it is least soluble in water.

What is the solubility of salt in water at 25 C?

357 mg/ml
Maximum solubility of NaCl in water at 25°C is 357 mg/ml. NaCl is unusual in that its solubility does not increase appreciably with temperature, since at 100°C, the solubility is 384 mg/ml. 1 The solubility of NaCl in water is decreased by adding HCl; it is almost insoluble in concentrated HCl.

Does salt dissolve in methanol?

Concerning the salt + alcohol systems, it is worthwhile first to notice the inverse salt solubility temperature dependence the salt solubility decreases with rising temperature for salts NaCl in methanol and NaBr in methanol and ethanol.

## Which salt has the highest solubility?

Ammonium chloride salt has the highest solubility at this temperature.

• From the given table, it is clear that, at the temperature of 293 K, the solubility of each salt is:
• The solubility of Potassium nitrate at 293 K is = 32 g.
• The solubility of Sodium chloride at 293 K is = 36 g.

### Which salt has the highest and the lowest solubility at 323 K *?

From the above data it is clear that at 323 K, salt Y has the highest solubiltiy in water while salt Z has the lowest soubility.

Which is more soluble Na2SO4 or mgso4?

Alkali metal sulphates are more soluble as compared to alkaline earth metal sulphates. Thus, Na2SO4 is most soluble.

What do you mean by the solubility of a salt at 20 C is 36?

This means that 36.0g of sodium chloride dissolves in 100g of water to form a saturated solution at 20 degree celsius.

## What is soluble in water at 25 degrees Celsius?

All sodium, potassium, and ammonium salts are soluble. All nitrates, acetates and perchlorates are soluble.

### Why is NaCl insoluble in methanol?

The attraction between the Na+ and Cl− ions in the solid is so strong that only highly polar solvents like water dissolve NaCl well….Aqueous solutions.

Solubility of NaCl (g NaCl / 1 kg of solvent at 25 °C (77 °F))
Liquid ammonia 30.2
Methanol 14
Ethanol 0.65
Dimethylformamide 0.4

Are salts soluble in alcohol?

Adding salt to water/alcohol mixtures can separate them into layers. Even though water and alcohol mix well together, alcohol and salt do not. When salt is added to the solution, the salt dissolves in the water but not in the alcohol.
