Question 13 (2 points) A basic buffer is prepared by adding 0.7185 g of NH4Cl to 1.00 L of 0.4490 M NH3. Kb (NH3) = 1.8 x 10-5. Calculate the pH of the buffer. Provide your answer to two places after the decimal. Your Answer: Answer Hide hint for Qugstion 13 You must convert the mass of ammonium chloride into molarity. Also, you need to calculate the K, of ammonium ion from the Kb value of ammonia.
