I was given a chemical equation and know that A 100.0 mL aliquot of 0.200 M aqueous potassium hydroxide is mixed with 100.0 mL of 0.400 M aqueous magnesium nitrate.
2KOH(aq) + 1Mg(NO3)2(aq) -> 1Mg(OH)2 + 2KNO3
I am then asked to calculate the concentration of each ion remaining in solution after precipitation is complete. The ions are K+, OH-, Mg2+, NO3-. anyone have any hints on how to do this because 0M for K+ is apparently incorrect
