5 4 What is the total concentration of ions in a 50x10 M zin
5. (4) What is the total concentration of ions in a 5.0x10 M zinc oxalate solution providing that the salt is fully dissociated and zine and oxalate ions are the only ions present?
Solution
ZnC2O4 -------------> Zn+2 + C2O4-2
[ZnC2O4] = 5.0 x 10-5 M
[Zn+2] = 5.0 x 10-5 M
[C2O4-2] = 5.0 x 10-2 M
total ions concentration = 0.05 + 0.05 = 0.1 M
answer = 0.10 M
