Question- When blood is donated, sodium oxalate solution is used to precipitate Ca2+, which triggers clotting. A 116mL sample of blood contains 9.7*10^-5g Ca2+/mL. A technologist treats the sample with 100 mL of 0.1550M Na2C2O4. Calculate [Ca^2+] after the treatment. (CaC2O4*H2O Ksp = 2.30*10^-9)
It is not a question in the book, so I just need the full solution of deriving!
