A chemistry graduate student is given 125. mL of a 1.40 M benzoic acid (HC,H,CO2) solution. Benzoic acid is a weak acid with K¸=6.3 × 10 What mass of NaC,H,CO, should the student dissolve in the HC H,C0, solution to turn it into a buffer with pH = 4.28? You may assume that the volume of the solution doesn't change when the NaC H,CO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
