Assuming methanol to undergo self dissociation to give `H^(+) & CH_(3)O^(-)` what will be its percentage dissociation if a 0.5 M solution has `[H^(+)]` equal to `2.5xx10^(-4) M`.

Options

A. 0.05
B. 0.1
C. 0.0005
D. 0.0001

Answer

1

Explanation

`{:(CH_(3)OH,hArr ,CH_(3)O^(-),+,H^(+)),(0.5 M,,x,,x=2.5 xx10^(-4)):}`
% dissociation `=(2.5xx10^(-4))/0.5 xx100 =0.05`
