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. Na CO2(aq) + H2SO (aq) →H2O(1)+ CO2(8)+ Na 50 (aq) What is the molarity of the H,SO 2 6. A solution...

You titrated a 22.00 mL solution of 0.0300 M oxalic acid with
freshly prepared solution of KMnO4. If it took 48.99 mL of this
solution, what is the molarity of the KMnO4?
0.022 L of 0.300 M oxalic acid
(0.022)(0.03) = 0.00066 mol oxalic acid
0.0006 mol oxalic acid x (2 mol KMnO4)/(5 mol oxalic acid)=
0.000264 mol KMnO4
0.000264 mol/0.04899 L = 0.05388855 M KMnO4
= 0.005388 M KMnO4
