Question

A metal strip x is dipped in a blue coloured salt solution yso4. after sometime, a layer of metal y from the salt solution is formed on the surface of metal strip x. metal x is used in galvanization whereas metal y is used in making electric wires. metal x and metal y together form an alloy z. (a) what could metal x be? (b) what could metal y be? (c) name the metal salt yso4 (d) what type of chemical reaction takes place when metal x reacts with salt solution yso4? write the equation of the chemical reaction involved.

Answer 1

X is zinc, y is copper , the metal salt is cuso4, this is called displacement reaction , cuso4 + zn - znso4 +cu
