Question

A strip of metal x is dipped in blue coloured salt solution yso4 after some time alayer of metal y from the salt solution is formed on the surfaceof metal strip x metal x iused in galvanisation whereas metal y is used in making electric wires metal x and metal y together form an alloy z [a]what could metal x and y be [b]name the metal salt yso4 [d] what type of reaction takes place when metal x reacts with salt solution yso4 and write the eqution [e] name the alloy z

Answer 1

1. metal X is zinc
2. metal y is copper
3. metal salt YSO4 is copper sulphate
4. Displacement reaction takes place.chemical equation is given as follows

Zn(s) +CuSO4 (ag) --> ZnSO4 (s) + Cu (s)

5.the alloy is brass
