Titration of Acids and Bases 5. Sodium carbonate is a reagent that may be used to standardize acids in the same way you used KHP in this experiment. In such a standardization, it was found that a 0.512 sample of sodium carbonate required 26.30 mL of a sulfuric acid solution to reach the end point for the reaction.

= O ACIDS AND BASES Calculating the pH at equivalence of a titration A chemist titrates 60.0 mL of a 0.1536 M butanoic acid (HC,H,CO2) solution with 0.8565 M NaOH solution at 25 °C. Calculate the pH at equivalence. The pk, of butanoic acid is 4.82. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of NaOH solution added. pH = x...
