16. If you have a solution with a pH of 3, what is the [OH^-] concentration? A) 1times 10^-11M B) 1times 10^-10M C) 1times 10^-7M D) 1times 10^-14M Ansv wer: A ) 1times 10^-11M

Question

Answer 1

To find the

concentration from the given pH, we can use the relationship between pH, pOH, and the ion product of water (

).Given:- pH = 3Step 1: Calculate pOH.pOH = 14 - pHpOH = 14 - 3pOH = 11Step 2: Calculate

concentration.

Therefore, the

concentration is
