Chapter 13, Problem 13.14P

Interpretation Introduction

Interpretation:

Molarity of ${\text{CN}}^{-}$ in $12.7\text{ mL}$ of unknown sample has to be determined.

Concept Introduction:

EDTA or ethylenediaminetetraacetic acid is used for titration of majority of metals with help of formation of strong metal complexes in the ratio of $1:1$. It is utilized to bind metals, most commonly used in industrial processes. It is also used for prevention of food oxidation and in environmental chemistry.

Formula to calculate molarity of solution is as follows:

  $\text{Molarity of solution}\left(\text{M}\right)=\frac{\text{Moles of solute}}{\text{Volume }\left(\text{L}\right)\text{ of solution}}$        (1)
