Question

[OH^-] ion concentration of 0.5M aqueous HCl solution is

Answer 1

Explanation:

OH- known as the basicity of an acid

it is the number of ionizeable H+ ion in an acid

in HCl there is 1 H

so 0.5 M HCl

means

in 1 litre of solution there is 0.5 moles of HCL

HCL dissociate in water as H + and CL - ions

so

0.5molHCl/1L×1H+/1molHcl

so on calculating the OH- concentration is0.5M
