medium
Write word equations and then balanced equations for the reaction taking place when -
$(a)$ dilute sulphuric acid reacts with aluminium powder.
$(b)$ dilute hydrochloric acid reacts with iron filings.
Option A
Option B
Option C
Option D
Solution
$(a)$ Sulphuric acid $+$ Aluminium $\rightarrow$ Aluminium sulphate $+$ Hydrogen
$3{{H}_{2}}S{{O}_{4(aq)}}\,+A{{l}_{(s)}}\to $ $A{{l}_{2}}{{(S{{O}_{4}})}_{3(aq)}}\,+\,3{{H}_{2(g)}}$
$(b)$ Hydrochloric acid $+$ Iron $\rightarrow$ Ferric chloride $+$ Hydrogen
$6 HCl _{(a q)}+2 Fe _{(s)} \longrightarrow 2 FeCl_{3(aq)}+3 H _{2(g)}$
