Phosphate buffer ph temperature
WebTemperature °C pH : Temperature °C pH : pH 2 Buffer (glycine) 20: 2,000 : pH 6 Buffer (phosphate) 15: 6,022 (J/2800) 25: 2,101 (J/2840) 20: 6,000 : 25: 5,976 : 30: 5,957: pH 3 … 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
