What is solubility of salt ? Explain classification of salt based on solubility ?
Solution
Each salt has its own characteristics. The no. of moles of solute disown in 1 lit. at definite temperature is called solubility of salt.
salt
$(i)$Soluble salts
– Solubility is more than $0.1 \mathrm{M}$
– Such salts are in the form of ion ionization.
e.g. $\mathrm{NaCl}, \mathrm{CaCl}_{2}, \mathrm{CaF}_{2}$
$(ii)$ less soluble salt
– Solubility is more than $0.01 \mathrm{M}$ and less than.
– Possess ionic equilibrium e.g. $\mathrm{Ca}(\mathrm{OH})_{2}, \mathrm{MgSO}_{4}$
$(iii)$ sparingly Soluble salt
– Solubility is less than $0.01 \mathrm{M}$
Sparingly soluble e.g. $\mathrm{AgCl}, \mathrm{Mg}(\mathrm{OH})_{2}, \mathrm{BaSO}_{4}$
The solubility of salts change with temperature.
