Answer to Question #241783 in Inorganic Chemistry for Mike

Question

calculate the concentration of nitrate ion in a solution of 0.10 m barium nitrate solution following the electroneutrality principle

Answer 1

According to the electroneutrality principle, barium nitrate can be dissociated as

Ba(NO₃)₂ → Ba₂⁺ + 2NO₃^-

So if the concentration of Barium Nitrate is 0.10 M then according to the above equation the concentration of nitrate ion will be

NO₃^- = 2 $\times$ 0.10 = 0.20 M
