Chapter 18, Problem 18.165P

(a)

Interpretation Introduction

Interpretation:

The strong and a weak monoprotic acid have to be differentiated when Electrical conductivity of an equimolar solution of each acid is measured.

Concept introduction:

Measuring conductivity:

Conductivity of the solution is depends on the ions in the solution, if the ions are more, the conductivity is increases, if the ions are less conductivity decreases. Strong base has a higher conductivity because it is dissociates completely and weak base has lower conductivity because less dissociation.

(b)

Interpretation Introduction

Interpretation:

The strong and a weak monoprotic acid have to be differentiated when equal molarities of each are tested with pH paper.

Concept introduction:

pH:

A solution may be acidic and basic depends on relative strength of anions as an acid or base. Anions and cations can be acidic, basic and netural. Acidic have $\text{pH < 7}$, basic have $\text{pH > 7}$ and netural have $\text{pH=7}$.

If the $\text{pH}$ of the solution is less, it is more acidic, if the $\text{pH}$ of the solution is high, it is more basic.

(c)

Interpretation Introduction

Interpretation:

The strong and a weak monoprotic acid have to be differentiated when Zinc metal is added to solutions of equal concentration.

Concept introduction:

Reactivity:

Strong acids will react more vigorously with metals or carbonates and produces hydrogen gas whereas weak acids will react less with metals or carbonates.
