I have the Analytical Chemistry book written by Skoog. The examples he shows are very brief and I have a hard time understanding.

Question: Calculate the solubility of Ba(IO3)2 in a solution prepared by mixing 200 mL of 0.0100 M Ba(NO3)2 with 100 mL of 0.100 M NaIO3.

I have the solution but I do not understand it. Can someone please explain the theory behind each step if it isnt too much? Ex: Why are you calculating a certain ion concentration and not the next. Thank you.

write down a balanced reaction and calculate stoichiometry first. Note, this is reaction with a limiting reagent. Then calculate concentration of reagent in excess. Finally put it in the solubility product equation.

Ok. I understand that this is a problem with a limiting reagent but how many reactions are there or what should I be looking for? Also, why is the concentration of the reagent of excess important to the reaction? Are there problems where one must study other situations. Sorry, I am teaching myself and Skoog isn't doing a good job in assisting me neither is my professor.

Start googling for a common ion effect.
