Ph of hydroxide solution
WebpHis a measure of the hydrogen ion (H+) activity in a solution and, therefore, its acidity or alkalinity. Values for some common bases: Sponsored Links Related Topics Environment … 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. Comment ( 4 votes) Upvote
