A 1000 ml of 100 mm phosphate buffer ph 75 pka2 72 you are, Ask an Expert

Academics

A 100.0, mL of 10.0 mM phosphate buffer, pH 7.5 (pKa2 = 7.2). You are provided with 0.200 M KOH and 0.100 M KH2PO4 solutions. Calculate volume of KOH and KH2PO4 solutions. (HINT: determine the mole ratio of the salt (K2HPO4) and acid ( KH2PO4) using buffer equation, then calculate the volume of KOH and KH2PO4 required) Please also note that the K2HPO4 is formed by mixing KOH and KH2PO4 together.

KOH + KH2PO4 --> K2HPO4
