In which one of the following pairs, both oxides are acidic?
  1. $\mathrm{CO}, \mathrm{CO}_2$
  2. $\mathrm{SnO}, \mathrm{PbO}_2$
  3. $\mathrm{GeO}, \mathrm{SiO}_2$
  4. $\mathrm{SnO}, \mathrm{PbO}$

Solution

Acidic oxides $=\mathrm{CO}_2, \mathrm{SiO}_2, \mathrm{GeO} Amphoteric oxides $=\mathrm{SnO}, \mathrm{PbO}, \mathrm{PbO}_2$ Neutral oxides $=\mathrm{CO}$
