How does a ph of 3 differ from ph of 4
WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer. Question: 3. By what factor does a change of 1 pH unit change the concentration of H30-? For example how does the [H3O+] at a pH of 3 differ from a pH of 4? 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.
