Question

The atomicity of one of the acids below is one? A. H2So4 B. H2Co3 C. H2C2O4 D. CH3COOH.

Answer 1

If you are asking which is the ONLY monoprotic acid, this is `"option D."`

Explanation:

And so we can write the acid-base reaction for all the options...

`H_2SO_4(aq) + 2NaOH(aq) rarr 2H_2O + Na_2SO_4(aq)`

`H_2CO_3(aq) + 2NaOH(aq) rightleftharpoons 2H_2O(l) + Na_2CO_3(aq)`....

`H_2C_2O_4(aq) + 2NaOH(aq)rightleftharpoonsNa_2C_2O_4(aq) +2H_2O`
..again, formation of oxalate ion is disfavoured..

`H_3C-CO_2H + NaOH(aq) rightleftharpoons H_3C-CO_2^(-)Na^(+) + H_2O`

Acetic acid is the only monoprotic acid, and requires the ONE equiv of base for equivalence....
