If the pH of a solution is 2.7 what is the pOH

The answer to your question is pOH = 11.3

Explanation:

Data

pH = 2.7

pOH = ?

pH measures the hydronium concentration [H₃O⁺]. The scale of pH goes from 0 to 14. If the solution has a pH from 0 to 6.9 the solution is an acid, if the pH = 7, the solution is neutral and if the pH goes from 7.1 to 14 the solution is an alkali,

Formula

pH + pOH = 14

-Solve for pOH

pOH = 14 - pH

-Substitution

pOH = 14 - 2.7

-Result

pOH = 11.3

pH + pOH = 14 = > pOH = 14 - pH = 14 - 2.7 = 11.3
