Define solubility

(a) Define solubility of a substance .How does it vary with temperature ? (b) what do you understand by the statement " the solubility of copper sulphate in water at 20^(@)C is 20.7 g"? ( c) what is the effect of temperature on the solubilty of solids in liquids ?

(a) What happens when MgSO_(4).7H_(2)O is heated? Write the appropriate equation (b) Define solublity.

solubility and solubility product,calculation OF solubility in different cases,solubility in presence OF common ion

If the solubility of a solid in a liquid is endothermic then the solubility will be increased if

Define molar solubility.

Define the term 'solubility of a solute in water. If 10 g. of a solute is added to 100 g. of water at (50^@C) and stirred, it is seen that the total solute dissolves at that temperature giving an unsaturated solution. Is 10 g, the solubility of the solute in water. Give reasons.
