(Dilute sulphuric acid, sodium carbonate, Zinc, sodium sulphite, Lead, calcium carbonate)
Give the equation for the reaction by which you could obtain zinc carbonate (two steps required).
उत्तर
\[\ce{\underset{Zinc}{Zn}+\underset{Dil.sulphuric acid}{H2SO4}->\underset{Zinc sulphate}{ZnSO4} + H2\uparrow}\]
\[\ce{\underset{Zinc sulphate}{ZnSO4} + \underset{Sodium carbonate}{Na2CO3}-> \underset{Zinc carbonate}{ZnCO3}+\underset{Sodium sulphate}{Na2SO4}}\]
