Question

Give the name and formulae of two (i) strong monobasic acids and (ii) two weak dibasic acids.

Answer 1

1. An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance.
2. Monobasic acids are acids that have only one replaceable hydrogen atom.
3. Dibasic acids are acids that have two replaceable hydrogen atoms.

Example of strong monobasic acid:

1. Hydrochloric acid $\left(\mathrm{HCl}\right)$,
2. Nitric acid $\left({\mathrm{HNO}}_3\right)$

Example of weak dibasic acid:

1. Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$
2. Oxalic acid $({\mathrm{C}}_2{\mathrm{H}}_2{\mathrm{O}}_4)$

Hence, these are the name and formulas of strong monobasic acid and weak dibasic acid.
