Title: how to find the concentration of a solution given the pH
Post by: nevada on Oct 27, 2013
determine  the concentration of a solution of a weak acid HCLO2 (ka=1.10x10^-2) if it has a ph of 1.391


i have no idea how to solve this, can you please explain the steps



Thanks

Could you show us how?

pH= -log[H+]
[H+]=10^-pH

plug pH in the equation and you'll get H+ concentration. do you need more help?
