Question

if pH solution is2,what is the concentration of OH in the solution​

Answer 1

Answer:

Find the [OH-] given the pH or pOH. You are given that the pH = 4.5. Find the hydroxide ion concentration of a solution with a pOH of 5.90. To solve this, use a scientific calculator and enter 5.90 and use the +/- button to make it negative and then press the 10x key.

Explanation:

pH =2

pH+pOH=14

Hence pOH =14-2=12

Log[OH-] = 12

[OH-] =10^-12
