🤓 Based on our data, we think this question is relevant for Professor Eroy-Reveles' class at UCSC.
We're asked to write the equilibrium-constant expression for the reaction between an acid, HA and a base, B.
Recall that the equilibrium constant is the ratio of the products and reactants:
Note that solid and liquid compounds are ignored in the equilibrium expression.
First, we need to write the equation for the reaction between HA and B, recall that:
▪ B is a base and based on Bronsted-Lowry definition it is a proton (H+) acceptor.
▪ HA is an acid and based on Bronsted-Lowry definition it is a proton donor.
The equation is:
Equal quantities of 0.010M solutions of an acid HA and a base B are mixed. The pH of the resulting solution is 9.3.
Write equilibrium-constant expression for the reaction between HA and B.
