1.	An element A which is a part of common salt and kept under kerosene reacts with another element B of atomic number 17 to give a product C. When an aqueous solution of product C is electrolysed then a compound D is formed and two gases are liberated. (a) What are A and B ? (b) Identify C and D. (c) What will be the action of C on litmus solution ? Why ? (d) State whether element B is a solid, liquid or gas at room temperature. (e) Write formula of the compound formed when element B reacts with an element E having atomic number 5. Lakhmir Singh Chemistry Class 10
Answer» s sodium B is chlorine. (b) C is sodium CHLORIDE and D is sodium hydroxide(c) C will have no effect on LITMUS solution since it is neutral in NATURE(d) B is a gas at room TEMPERATURE(e) EB3 or BCl3
