Question

(a) Name three common strong acids.

(b) Name three common strong bases.

(c) What is a characteristic behavior of a strong acid or a strong base?

Short answer

(a)$\mathrm{HCl},{\mathrm{H}}_2{\mathrm{SO}}_4\mathrm{and}{\mathrm{HNO}}_3.$

(b)$\mathrm{NaOH},\mathrm{KOH}\mathrm{and}\mathrm{Ca}{\left(\mathrm{OH}\right)}_2.$

(c)Strong acid or strong base both can completely dissociate in water.

Step-by-step solution

Definition of acid and base

Acids are those compounds that give${\mathbf{\text{H}}}^{\mathbf{\text{+}}}$ ions in aqueous solution.

Bases are those compounds that give${\mathbf{\text{OH}}}^{\mathbf{\text{-}}}$ ion in an aqueous solution.

Names of three common strong acids

The names of the three strongest acids are:

1. Hydrochloric acid$\left(\mathrm{HCl}\right)$
2. Sulfuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$
3. Nitric acid$\left({\mathrm{HNO}}_3\right)$

Names of three common strong bases

The names of the three strongest bases are:

1. Sodium Hydroxide$\left(\text{NaOH}\right)$
2. Potassium Hydroxide $\left(\text{KOH}\right)$
3. Calcium Hydroxide$\left(\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\right)$

Predict the behaviour of a strong acid or a strong base

The characteristic behavior of a strong acid and base is both of them can completely dissociate in water.

Strong acids give 100% dissociation into${\mathbf{H}}^{+}$ and${\mathbf{\text{X}}}^{\mathbf{\text{-}}}$ of HX acid.

A strong base gives 100% dissociation into${\mathbf{\text{M}}}^{\mathbf{\text{+}}}$ and${\mathbf{\text{OH}}}^{\mathbf{\text{-}}}$ of MOH base.
