If the pOH of a solution is 4.5 what is the ph?

The answer to your question is pH = 9.5

Explanation:

Data

pOH = 4.5

pH = ?

pH measures the hydronium concentration [H₃O⁺]. The scale of pH goes form 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 pH

pH = 14 - pOH

-Substitution

pH = 14 - 4.5

-Result

pH = 9.5
