Phosphate buffer ph 2.0
WebThis leaves phosphate with useful buffering regions of 2.0 ≤ pH ≤ 3.1 and 6.2 ≤ pH ≤ 8.0. As long as the mobile phase is within one of these ranges, phosphate will be an effective buffer. But if we want a mobile phase at other pH values, phosphate is not a very good buffer. WebPhosphate buffer solution pH 2.0. 4007900.
