Question

A metal hydroxide of molecular formula m(oh)4 is 50 ionised

Answer 1

Hi, this your question is like not complete.

But I hope it is reading like this;

A metal hydroxide of molecular formula m(oh)4 is 50 ionised. its 0.0025M solution will have the pH.

So here, degree of ionization is 50% or 0.5

So according to the equation, the hydroxide, OH- concentration is now given by 0.0025 x 4= 0.01M.

But the equilibrium concentration is given by C∝ where C is the concentration and ∝ is the degree of ionization.

= 0.01 x 0.5 = 0.005 M

pOH= -log 0.005

pOH= 2.3

but pH= 14 - 2.3

    pH= 11.7
