The solubility of `K_(2)SO_(4)` in water is `16 g` at `50^(@)C`. The minimum amount of water required to dissolve `4 g K_(2)SO_(4)` is:

The solubility of a salt in water is 40 g at 30^(@)C . The amount of water required to dissolve 120 g at the same temperature is:

The solubility of BaSO_(4) in water is 2.33 g 100 mL^(-1) . Calculate the percentage loss in weight when 0.2g of BaSO_(4) is washed with a. 1L of water b. 1L of 0.01 NH_(2)SO_(4).[Mw_(BaSO_(4)) = 233 g mol^(-1)]

What is the minimum volume of water required to dissolve 1g of calcium sulphate at 298. K_(sp) for CaSO_4 is 9.1xx10^(-6) .

Na_(2)SO_(4) is water soluble but BaSO_(4) is insoluble because :

Determine the osmotic pressure of a solution prepared by dissolving 0·025 g of K_(2)SO_(4) in 2 litres of water at 25^(@)C , assuming that K_(2)SO_(4) is completely dissociated. (R=0.0821 " Lit-atm K"^(-1) "mol"^(-1)," mol. wt. of " K_(2)SO_(4)=174"g mol"^(-1))

12 g of H_(2)SO_(4) are dissolved in water to make 1200 ml of solution. The normality of the solution is
