Question

What are the strongest acids and bases?

Answer 1

Strong acids:

1. The acids which completely dissociates into its respective ions when dissolved in water are known as a strong acid.
2. The dissociation of strong acid in water is shown below.
   $\mathrm{HA}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_3{\mathrm{O}}^{+}\left(\mathrm{aq}\right)+{\mathrm{A}}^{-}\left(\mathrm{aq}\right)$
3. An acid's strength is determined by the amount of hydrogen ion produced by the reaction.
4. A few examples of strong acids are Hydrochloric acid, Nitric acid, Sulfuric acid etc.

Strong base:

1. The base which completely dissociates into its respective ions when dissolved in water is known as a strong base.
2. The dissociation of a strong base in water is shown below.
   $\mathrm{BOH}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{B}}^{+}\left(\mathrm{aq}\right)+{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)$
3. The strength of the base is based on the ${\mathrm{OH}}^{-}$ ions produced from the reaction.
4. An example of strong bases is Sodium hydroxide, Potassium hydroxide, Lithium hydroxide etc.
