Some properties of sulphuric acid are listed below. Choose the property A, B, C or D which is responsible for the reactions (i) to (v). Some properties may be repeated:
- Typical acid
- Dehydrating agent
- Non-volatile acid
- Oxidizing agent
- \[\ce{C12H22O11 + nH2SO4 -> 12C + 11H2O + nH2SO4}\]
- \[\ce{S + 2H2SO4 -> 3SO2 + 2H2O}\]
- \[\ce{NaCl + H2SO4 -> NaHSO4 + HCl}\]
- \[\ce{CuO + H2SO4 -> CuSO4 + H2O}\]
- \[\ce{Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2}\]
The following is the typical property of dilute acid. Complete it by inserting suitable words:
\[\ce{Carbonate/hydrogen carbonate + Acid -> \underline{\phantom{.......}} + \underline{\phantom{.......}} + \underline{\phantom{.......}}}\]
