2. 112004 ? Assume volumes are auart A sample of pure KHC_(2)O_(4)cdot H_(2)C_(2)O_(4)cdot 2H_(2)O (three replaceable hydrogens)requires 46.2 mL of 0.100 M NaOH for titration.How many milliliters of 0.100 M KMnO_(4) will the same-size sample react?

Question

Answer 1

To solve this problem, we need to determine the stoichiometry of the reaction between

and

, and then use the titration data to find the volume of

required.Given information:- The sample of

requires 46.2 mL of 0.100 M NaOH for titration.Step 1: Determine the stoichiometry of the reaction between

and

.The balanced chemical equation for the reaction between

and

is:

Step 2: Calculate the moles of

in the sample.Moles of

= (Volume of NaOH × Concentration of NaOH × Stoichiometry) / Volume of sampleMoles of

= (46.2 mL × 0.100 M × 5) / 100 mL = 0.0231 molStep 3: Calculate the volume of 0.100 M

required to react with the same-size sample.Volume of

= (Moles of

× Stoichiometry of

) / Concentration of

Volume of

= (0.0231 mol × 2) / 0.100 M = 0.462 L = 462 mLTherefore, the same-size sample of

will react with 462 mL of 0.100 M

.
