16. What is the pH of a buffer made by combining 230 mof 0.41 M NaC2H02 with 110 mL of0.34 M HC2HO? The Ka of acetic acid is 1.75 x 10 17. A5.80-g sample of homogentisic acid, a weak organic acid having K -4.0 x 105, is dissolved in 25.00 mL of water and its pH is measured to be 2.130. What is the molar mass of homogentisic acid?

please show show work, very confused! will RATE
Problem 1. You are asked to prepare a pH = 10.0 buffer starting from 517 mL of water to which 21.8 g of ammonia have been added. The buffer will be prepared by the addition of ammonium chloride. The Kb of ammonia add to water is 1.99x105. Assume that the volume does not change on the addition of ammonia or ammonium chloride. (a) Write the balanced net ionic equation for ammonia added...
