🤓 Based on our data, we think this question is relevant for Professor Billman's class at Abilene Christian University.

Solution: A mixture of NaCN and NaHSO4 consists of a total of 0.60 mol. When the mixture is dissolved in 1.0 L of water and comes to equilibrium the pH is found to be 9.6.Find the amount of NaCN in the mixture.

Problem

A mixture of NaCN and NaHSO4 consists of a total of 0.60 mol. When the mixture is dissolved in 1.0 L of water and comes to equilibrium the pH is found to be 9.6.

Find the amount of NaCN in the mixture.

Solution

We are asked to calculate the amount of NaCN in a mixture of NaCN and NaHSOconsisting of a total of 0.60 mol. When the mixture is dissolved in 1.0 L of water and comes to equilibrium the pH is found to be 9.6.

NaCN and NaHSO4  are both ionic compounds of sodium with conjugate bases of weak acid CN- and strong acid HSO4-


The dissociation of NaCN and NaHSOare as follows:

NaCN (aq) → Na+ (aq) + CN- (aq)

NaHSO4(aq) →  Na+(aq) + HSO4-(aq)
