pH value of a solution, whose hydronium ion concentration is 6.2 xx 10 – InterviewSolution

1.	pH value of a solution, whose hydronium ion concentration is 6.2 xx 10^(-9) mol/l, is
Answer» 6.21 7.21 7.75 8.21 Solution :`[H_(3)O^(+)]` MEANS `[H^(+)] = 6.2 xx 10^(-9)` mol/l `PH = -log (6.2 xx 10^(-9)) = 8.21`.
