Ph of 3 to 5
WebAnswer (1 of 4): A lower ph is always more acidic, due to the increased concentration of hydrogen ions in the solution/substance. If you look at most, acids, they have hydrogen in … WebJun 24, 2016 · Ksp = x ⋅ x c − x = x2 c −x. Now, as long as the initial concentration of the acetic acid, c, is significantly higher than the Ksp of the acid, you can use the approximation. c − x ≈ c → valid when c >> Ksp −−−−−−−−−−. In this case, the equation becomes. Ksp = x2 c. which gives you. x = √c ⋅ Ksp. Since x ...

The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is ...
