Zinc carbonate Choose one substance in each case which matches ttk• description ' (i) A normal salt formed when basic oxi& and acidic oxide react. (ii) An insoluble binary salt (iii) Insoluble carbonate (iv) An insoluble salt formed from two soluble salts (v) A salt which on heating leaves metal as reud1E. (b) How will you identify the following salts: calcium chloride, lead chloride and zinc chloride ? (c) State your observations and write balanced equations. (i) Sodium chloride solution is mixed with lead mtrate solution. (ii) Ethylene gas is passed through a solution of bromine in carmn tetrachloride. (iii) Sodium hydroxide is added to iron (Ill) sulphate solution. (iv) Chlorine is passed through a solution of potassium

Dear student,

(i) CaSO3( calcium sulphite) is a normal salt formed when CaO( basic oxide) and SO2( acidic oxide) reacts.
                   CaO + SO2  CaSO3

(ii) Zinc sulphide (ZnS) is a binary salt which is insoluble in water.

(iii) Zinc Carbonate( ZnCO3) is an insoluble carbonate.

(iv) ZnSO4(aq) + Na2CO3(aq) → Na2SO4(aq) + ZnCO3(s)
       Zinc sulphate and sodium carbonate both are soluble salts in water, but the product zinc carbonate is insoluble in water and is precipitated out.

(v) Silver nitrate decomposes when heated and gives silver metal
                          2 AgNO3(l) → 2 Ag(s) + O2(g) + 2 NO2(g)
