I'm sure you mean 0.35M solution. Do you know that 0.35M and 0.35m are not the same? This is a hydrolysis problem.
........CO3^2- + HOH ==> HCO3^- + OH^-
I.......0.35M..............0.......0
C.......-x.................x.......x
E.......0.35-x.............x.......x
Kb for CO3^- = (Kw/k2 for H2CO3) = (x)(x)/(0.35-x). Substitute and solve for x = (OH^-) an convert to pH.
Why is the last step is convert to pH? We are trying to find the hydroxide-ion concentration?not the pH
Nvm figured it out
