Barium hydroxide is a strong base for both stages of dissociation: Ba(OH)_2(s) -> Ba^{2+}+2OH^- So the solution will have 0.20 M hydroxide ions.

### Calculating pH of a Ba(OH)2 Yeah Chemistr

1. Ba(OH)2 is the limiting reactant, which means all of the HCl is used up. That alone tells us the pH is above 7, as Ba(OH)2 is alkaline and there is no acid left, I'm confused because if Ba(OH)2 is the limiting reactant, shouldn't it be used first and leave acid behind? \$\endgroup\$ - space Apr 22 '18 at 9:2
