In an acid-base titration, 33.12mL of 0.1177 M H2C2O4 was titrated with 0.2146 M NaOH to the end point. What volume of NaOH solution was used? NaOH(aq)+H2C2O4(aq) ---> Na2C2O4(aq) + H2O(l)
Homework Answers
This question is based on the molarity, volume and moles concept. We evaluate the moles of H2C2O4 and then find the volume of NaOH.

24A) 40mL of 0.2 M formic acid is titrated with a strong base
(NaOH= 0.5 M). Determine the pH before any base has been added.
Please show steps and please explain why the answer is what it
is.
24B) The 40mL 0.2 M formic acid is titrated with a 6.0mL of
strong base. Here NaOH can be treated as a conjugate base and
formic acid is the acid.

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
