Chapter 5, Problem 99SAE

Interpretation Introduction

(a)

Interpretation:

The given symbol $(\rightleftharpoons )$ needs to be explained.

Concept introduction:

Reaction is the phenomenon which takes place between two or more chemical species to form the product. The type of chemical reactions depends on the nature of reacting species, for example, if one reactant forms two products, the reaction is termed as dissociation reaction. If two reactants react to form a single product, the reaction is termed as combination reaction.

Interpretation Introduction

(b)

Interpretation:

The given symbol $\left(\left[\right]\right)$ needs to be explained.

Concept introduction:

There are symbols to represent the parameterslike pressure, temperature, or concentration in the chemistry.

The pressure is denoted by symbol P and temperature of a substance is denoted by symbol T. The concentration of any substance is denoted by write its symbol in the square brackets for example, the symbol for the concentration of species A is $\left[\text{A}\right]$.

Interpretation Introduction

(c)

Interpretation:

The term spectator ion needs to be defined.

Concept introduction:

The ionic species present in the reaction can be in free state as cation or anion, or they can also combine to form a new neutral species. Here, cations are positive charged ions and anions are negative charged ions. When a cation reacts with an anion to form a new species, some of the cation or anion participates and some do not participate in the reaction.

Interpretation Introduction

(d)

Interpretation:

The term weak acid needs to be defined.

Concept introduction:

An acid is defined as a species that gives hydrogen ions in the aqueous solution. They are also termed as proton donor or electron acceptor. A strong acid completely dissociate into conjugate base and hydrogen ion as follows:

$\text{HA}\to {\text{H}}^{+}+{\text{A}}^{-}$
