Question

Which statement describes a 0.01 M LiOH( aq) solution?

Answer 1

Before answering the question, one should first calculate the pH for given concentration of LiOH.

As LiOH ionizes as,

                                 LiOH    →     Li⁺  +  OH⁻

So, the concentration of OH⁻  =  [OH⁻]  =  0.01
Also,
                               pOH  =  -log [OH⁻]

                               pOH  =  -log [0.01]

                               pOH  =  2
Whereas,
                               POH  +  pH  =  14
Or,
                               pH  =  14 - 2

                               pH  =  12
Result:
           As pH is greater than 7, so the solution is Basic.
