Chapter 4, Problem 4.84QP

(a)

Interpretation Introduction

Interpretation: The questions related to the given equation are to be answered.

Concept introduction: Concentration of a solution is expressed in the form of Molarity.

Molarity (M) is defined as the number of moles of given solute in a liter of solution. Molarity defines the molar concentration of the compound.

It is calculated by the formula,

$M=\frac{n}{V}$

Where,

• $M$ is Molarity.
• $n$ is number of moles of solute.
• $V$ is volume of solution.

To determine: The amount of ${\text{CN}}^{-}$ concentration in $\text{mg/L}$ in the water for the given reaction.

(b)

Interpretation Introduction

To determine: The amount of ${\text{AgNO}}_{\text{3}}$ to precipitate the chloride ion.
