Question

An aqueous solution contains an unknown concentration of $B a^{2 +}$ . When $50 m L$ of a $1 M$ solution of $N a_{2} S O_{4}$ is added, $B a S O_{4}$ just begins to precipitate. The final volume is $500 m L$ . The solubility product of $B a S O_{4}$ is $1 \times 10^{- 10}$ . Find the concentration of $B a^{2 +}$ in the original solution?
