Chapter 6, Problem 6.HE

(a)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

${\text{Na}}^{\text{+}}{\text{Br}}^{\text{\_}}$

Concept introduction:

Neutral solution:

The solution has $\text{pH}$ of 7 is known as neutral solution, it is neither acidic nor basic.

(b)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

${\text{Na}}^{\text{+}}{\text{CH}}_{\text{3}}{\text{CO}}_{\text{2}}^{\text{-}}$

Concept introduction:

Basic solution:

When the compound dissolved in water, then it forms hydroxide ions.  Thus solution is known as basic solution.  It react with acids.  Basic solution has $\text{pH}$ greater than 7.  More basic means it has $\text{pH}$ is close to 14.

(c)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

${\text{NH}}_4^{+}{\text{Cl}}_{}^{\text{-}}$

Concept introduction:

Acidic solution:

When the compound dissolved in water, then it forms hydrogen ions.  Thus solution is known as acidic solution.  It react with certain metal and bases.  Acidic solution has $\text{pH}$ less than 7.  More acidic means it has $\text{pH}$ is close to zero.

(d)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

${\text{K}}_{\text{3}}{\text{PO}}_{\text{4}}$

Concept introduction:

Basic solution:

When the compound dissolved in water, then it forms hydroxide ions.  Thus solution is known as basic solution.  It react with acids. Basic solution has $\text{pH}$ greater than 7.  More basic means it has $\text{pH}$ is close to 14.

(e)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

${\left({\text{CH}}_{\text{3}}\right)}_{\text{4}}{\text{N}}^{\text{+}}{\text{Cl}}^{\text{\_}}$

Concept introduction:

Neutral solution:

The solution has $\text{pH}$ of 7 is known as neutral solution, it is neither acidic nor basic.

(f)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

$\left({\text{CH}}_{\text{3}}\right){\text{N}}^{\text{+}}{\text{C}}_{\text{6}}{\text{H}}_{\text{6}}{\text{CO}}_{\text{2}}^{\text{-}}$

Concept introduction:

Basic solution:

When the compound dissolved in water, then it forms hydroxide ions.  Thus solution is known as basic solution.  It react with acids.  Basic solution has $\text{pH}$ greater than 7.  More basic means it has $\text{pH}$ is close to 14.

(g)

Interpretation Introduction

Interpretation:

If given compound is soluble in water, the solution be acidic or basic or neutral has to be identified.

$\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{3}}$

Concept introduction:

Acidic solution:

Acidic solution:

When the compound dissolved in water, then it forms hydrogen ions.  Thus solution is known as acidic solution.  It react with certain metal and bases.  Acidic solution has $\text{pH}$ less than 7.  More acidic means it has $\text{pH}$ is close to zero.
