Question

Find PH of a solution, having H+ ion concentration 7.586 x 10-⁵ M.

​

Answer 1

Hydronium ion concentration [H+] = 7.568×10^-5 M

pH of solution = - log([H+]) = - log(7.568×10^-5) = -(-4.1210) = 4.1210

Hence, pH of the given solution is 4.1210

Answer 2

Explanation:

Some scales, such as the traditional beam balance, measure mass directly by counteracting the downward force by another equal downward force on the opposite side of the pivot. On a beam balance, you add enough mass to the opposite pan to counterbalance the unknown mass. No force is measured.
