Question

Determine the hydroxide ion concentration in

a solution that is 0.00034 M Ca(OH)2.
Answer in units of M.

Answer 1

`0.00068M`

Step-by-step explanation:

Hello there!

In this case, according to the ionization of calcium hydroxide, a strong base:

`Ca(OH)_2\rightarrow Ca^(2+)+2OH^-`

Thus, since there is a 1:2 mole ratio of calcium hydroxide to hydroxide ions, we apply the following proportional factor to obtain:

`0.00034(molCa(OH)_2)/(L)*(2molOH^-)/(1molCa(OH)_2) \\\\=0.00068(OH^-)/(L)\\\\=0.00068M`
