Answer:
The answer to your question is pH = 9.5
Step-by-step 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
