प्रश्न
Give the name of a soluble lead salt and write the eqution for the action of heat on this salt. Write the equation for the preparation of nitric acid from potassium nitrate.
उत्तर
Lead nitrate is soluble salt. On heating lead nitrate the following reaction occurs:
\[\ce{2Pb(NO3)2(s) ->[\Delta] 2PbO(s) + 4NO2(g) + O2(g)}\]
Preparation of nitric acid from potassium nitrate:
\[\ce{KNO3 + H2SO4 ->[200°C] KHSO4 + HNO3}\]
