### 9.57

Why does the solution to chapter 9 question 57 use h20 (aq) when the problem gives it as h20 (l) and i don't believe h20 aq exists?

Im pretty sure that that is just a typo in the solutions manual and it should have an l because if you look at the value they use it is the value for H20(l) not (aq)
