WebCompare the pH of two solutions, one pH = 8 and the other pH = 11. Are these acids or bases? What can you say about their relative strengths? Which is stronger and by how much? 4. West of Pennsylvania, in Ohio, Indiana, and Illinois, many companies burn coal in order to produce electricity. WebOne way to start this problem is to use this equation, pH plus pOH is equal to 14.00. And we have the pOH equal to 4.75, so we can plug that into our equation. That gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25.
