WebAs the hydroxide ions increase, the base’s strength also increases. Bases tend to have a higher pH value. Sodium hydroxide, calcium carbonate, and potassium oxide are a few examples of bases. What Is a PH Scale? The pH scale (pH) is a numerical scale used to determine how acidic water solutions are. The pH scale is typically ranged from 0 to 14. WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with.
