Question 23: Calculate the Ka or Kb of the weak acids or bases as asked. Report your answers to two significant figures, and if you use scientific notation use this format: 0.0015 is 1.5E-3. A 0.129 M solution of a weak base has pH of 10.18. The Kb value of the base is 1.8E-9 × A 0.118 M solution of a weak acid has pH of 2.87. The Ka value of the acid is 1.6E-5✔
