A solution is made by a dissolving 16.8 g of sodium fluoride , NaF , in enough water to make exactly 500.ml of solution . Calculate the molarity of each species: NaF, Na+ and F-.

Expert Solution

molarity = W*1000/G.M.Wt * volume of solution in ml

= 16.8*1000/42*500

= 0.8M

NaF(aq) -------------> Na^+ (aq) + F^-(aq)

0.8M 0.8M 0.8M

[NaF] = 0.8M

[Na^+] = 0.8M

[F^-] = 0.8M
