Chapter 15, Problem 108QRT

(a)

Interpretation Introduction

Interpretation:

The given blanks have to be filled with suitable words.

Concept Introduction:

To carry out reactions that require a constant pH, a buffer solution is used. They are generally prepared by intermixing of weak base or weak acid with its salt. They have an ability to keep the pH constant.

(b)

Interpretation Introduction

Interpretation:

The given blanks have to be filled with suitable words.

Concept Introduction:

The $\text{pH}$ is defined as the negative logarithm to the hydrogen ion concentration and it tells the nature of the solution. The physical constant which is used to determine the strength of an acid is known as acid dissociation constant. It is denoted by $K_{\text{a}}$. The greater $K_{\text{a}}$ value, stronger is the acid.

(c)

Interpretation Introduction

Interpretation:

The given blanks have to be filled with suitable words.

Concept Introduction:

Lewis base is compound which is electron rich. It will donate the excess electrons to the acid. Lewis acid is the compound which is electron deficient. Lewis acid contains empty orbital and accepts lone pair of electrons.

(d)

Interpretation Introduction

Interpretation:

The given blanks have to be filled with suitable words.

Concept Introduction:

Solubility product relates the solubility of a salt with the concentration of ions present in the salt. Solubility product holds a direct relation with the solubility of the salt. The solubility product is the ability of the solid to dissolve in aqueous solution.

(f)

Interpretation Introduction

Interpretation:

The given blanks have to be filled with suitable words.

Concept Introduction:

Titration is an analytical method which is used to determine the strength of the unknown solution. Acid-base titration involves neutralization reaction between an acid and a base. The equivalence point of the acid-base titration can be accurately predicted by the $\text{pH}$-metric titration.
