Chapter 7, Problem 7.102SP

Interpretation Introduction

Interpretation:

The mass percent of alcohol in blood should be calculated, if $\text{8}\text{.76 mL}$ $\text{of 0}{\text{.04988 M K}}_{\text{2}}{\text{Cr}}_{\text{2}}{\text{O}}_{\text{7}}$ is required to completely react with $\text{10}\text{.002 g}$ blood sample.

Concept introduction:

Redox:

The reduction and oxidation reactions are occur simultaneously with in a single reaction is known as redox reaction.

Redox titration:

Redox titration is type of titration method to determine the amount of analyte that present in the given sample by redox reaction.

Mass percent:

The mass percentage is calculated by percentage ratio of taken mass of the analyte to actual mass of sample.

$\text{Mass}\text{percentage}\text{=}\frac{\text{Mass}\text{of}\text{analyte}}{\text{Mass}\text{ofthe}\text{sample}}\text{×100}$

Mole:

Mole of the compound present in the solution is calculated by molarity concentration of the compound multiplied with litre volume of solution.

$\text{Mole}\text{= Molarity}\text{×Liter}$
