# What sort of solution will result if one equiv of hydrochloric acid is added to one equiv of calcium hydroxide? And how does #pH# relate to #pOH# in such solutions?

##### 1 Answer

Well hydrochloric acid is an acid that gives one equivalent of hydronium ion.........so you will get a BASIC solution is you add one equiv of calcium hydroxide........

#### Explanation:

Whereas, calcium hydroxide gives TWO equivalents of hydroxide anion. The solution will thus be stoichiometric in

We could represent neutralization of calcium hydroxide by hydrochloric acid by the following stoichiometric equation.....

Calcium hydroxide is not particularly soluble in aqueous solution; on t'other hand, calcium chloride is soluble.......

As background, we know that in aqueous solution gives rise to an increase in the concentration of

A solution that is

.....if we take

But

And so..........

On rearrangement.......

And so our defining relationship.......
