Chapter 4: Q14E (page 216)

Indicate what type or types of reaction each of the following represents:

(a) \({H_2}O\left( g \right) + C\left( s \right) \to CO\left( g \right) + {H_2}\left( g \right)\)

(b) \(2KCl{O_3}\left( s \right) \to 2KCl\left( s \right) + 3{O_2}\left( g \right)\)

(c) \(Al{\left( {OH} \right)_3}\left( {aq} \right) + 3HCl\left( {aq} \right) \to AlC{l_3}\left( {aq} \right) + 3{H_2}O\left( l \right)\)

(d) \(Pb\left( {N{O_3}} \right)\left( {aq} \right) + {H_2}S{O_4}\left( {aq} \right) \to PbS{O_4}\left( s \right) + 2HN{O_3}\left( {aq} \right)\)

Short Answer

Expert verified

(a) Oxidation-reduction reaction

(b) Oxidation-reduction reaction

(c) Acid-base reaction

(d) Precipitation reaction.

Step by step solution

01

Oxidation–reduction reaction (a)

Carbon is oxidised from 0 to +2 state and hydrogen is reduced from +1 to 0 oxidation state.

02

Oxidation–reduction reaction (b)

Here oxygen is oxidised from -2 to 0 oxidation state and chlorine is reduced from +5 to -1 oxidation state. The reaction is called decomposition reaction.

03

Acid-base reaction (c)

Here the transfer of hydrogen and hydroxyl ions between reactants happens, leading to the formation of aluminium chloride and water.

04

Precipitation reaction (d)

The ions replace and form an insoluble product, lead sulfate. Hence the reaction is called a double displacement reaction.
