Solubility product constant of calcium iodate/common ion
effect.
I am unsure how to do this however I am only asking for help on
trial one as there are 4 total trials and I would like to be able
to do those on my own after I have learned how to do the work.
Thanks.
Also, could you provide the balanced equation for the titration
as well as the solubility equation for iodate?
