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.
$(a)$ 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
$6 HCl _{(a q)}+2 Fe _{(s)} \longrightarrow 2 FeCl_{3(aq)}+3 H _{2(g)}$
What effect does the concentration of $H^+_{(aq)}$ ions have on the nature of the solution ?
You have two solutions, $A$ and $B$. The $pH$ of solution $A$ is $6$ and $pH$ of solution $B$ is $8$. Which solution has more hydrogen ion concentration Which of this is acidic and which one is basic?
Why does an aqueous solution of an acid conduct electricity?
Which gas is usually liberated when an acid reacts with a metal? Illustrate with an example. How will you test for the presence of this gas ?
How is the concentration of hydroxide ions $(OH^-)$ affected when excess base is dissolved in a solution of sodium hydroxide ?
