1.	When a strip of red-brown metal X is placed in a colourless salt solution YNO3 then metal Y is set free and a blue coloured salt solution X(NO3)2 is formed. The liberated metal Y forms a shining white deposit on the strip of metal X. (a) What do you think metal X is ? (b) Name the salt YNO3. (c) What could be metal Y ? (d) Name the salt X(NO3)2. (e) What type of reaction takes place between metal X and salt solution YNO3 ? Lakhmir Singh Chemistry Class 10
Answer» tion:(a) Metal X is COPPER (Cu) (b) The SALT YNO3 is Silver Nitrate. (AgNO3)(C) Metal Y is silver (Ag)(d) The salt X(NO3)2 is Copper Nitrate. (e) Displacement reaction takes place between metal X and salt solution YNO3.The reaction is - Cu + AgNO3 → Cu(NO3)2 + Ag
