1.	An aqueous solution an unknown concentration of Ba^(2+) , When 50 mL of a 1 M solution of Na, S0, is added, BaSO_4 , just begins to precipitate. The final volume is 500 mL. The solubility product of BaSO_4is 1 xx 10^(-10). What is the original concentration of Ba^(2+)
Answer» `5 xx 10^(-9) M` `2 xx 10^(-9) M` `1.1 xx 10^(-9) M` `1.0 xx 10^(-10) M` SOLUTION :`1.1 xx 10^(-9) M`
