Determine the Ka value[H +]eqSolution 5 4.68 X 10-10 MDirectionsTake a 30.0 mL sample of 1.0 M NaOAc and place it in a beaker. Using a pH meter, measure the pH of the solution and record it in your lab notebook.Since Solution 5 did not initially contain any HOAc, Ka = ([H+][OAc-])/[HOAc] cannot be used to calculate Ka; it must be found by first determining Kb from Kb = ([HOAc][OH-])/[OAc-]

The concentration of hydroxyl ion is calculated as follows:

- Solution 5
  - 4.68 X 10^-10 M
Directions
- Take a 30.0 mL sample of 1.0 M NaOAc and place it in a beaker. Using a pH meter, measure the pH of the solution and record it in your lab notebook.
  - Since Solution 5 did not initially contain any HOAc, K_a = ([H⁺][OAc^-])/[HOAc] cannot be used to calculate Ka; it must be found by first determining K_b from K_b= ([HOAc][OH^-])/[OAc^-]
