Answer:

12.00

Explanation:

12.00 is the answer. our teacher went over this rn

Answer 2

The pH of calcium hydroxide solution of 0.005 molarity is 12.

To find:

The pH of calcium hydroxide solution of 0.005 molarity

Given:

Molarity=0.005

Formula to be used:

$pOH=-log[OH^-]$

Solution:

If you look at the formula of the compound there are two hydroxide ions for every calcium ion. So 0.005 M calcium hydroxide gives a solution of 0.010 M in hydroxide ion.

The log of this number would be the pOH. So,

$-log[0.01]=pOH\\2=pOH$

Thus,

$pH+pOH=14\\pH+2=14\\pH=12$

Answer:

pH = 12
