We’re being asked to determine the concentration of silver ions [Ag+] when 23 g of AgCN(g) are placed in 150 mL of 0.15 M nitric acid (HNO3).

We're going to calculate the concentration of silver ions using the following steps:

Step 1: Write the balanced reaction.
Step 2: Find the equilibrium constant (K) for the net ionic equation.
Step 3: Construct an ICE chart for the reaction.
Step 4: Write the K expression and calculate for [Ag+].


Step 1: Write the balanced reaction.

Reactants:

AgCN is composed of Ag+ and CN-

HNO3 is a strong acid and will completely ionize in the solution.

HNO3 → H+ + NO3-
