Determining the pH of Buffer Solutions Imagine you are given 50.0 mL of a 0.50 mol/L solution of HNO; and 50.0 mL of a 0.50 mol/L solution of KNO. Using the following steps, determine the pH of the resultant solution. Write on the back of this sheet if you need additional space. 1. Determine the initial concentrations of HNO2 and NO: 2. Write down the chemical equation for the dissociation of HNO2. 3. Using the ICE table below, fill in the initial, change, and equilibrium concentrations. Equation: Initial Change Equilibrium 4. Write the equilibrium expression for the K, of HNO: 5. Insert your equlibrium concentrations into the expression written above and solve for x (The K, of HNO, is 5.6 x 10) 6. Using the formula, pH = -log[H3O°), determine the pH of the buffer solution. %3D
