a yellow malleable alloy is made up of two metals A and B. On treatment with dilute sulphuric acid, A dissolves from the surface of the alloy to form a colourless solution. B remains undissolved and is found to have a reddish brown colour. identify metals A and B, Explain the reactions involved. I am not sure but is the metals A and B are copper and iron respectively?
A is Zinc and B is copper.
Yellow malleable alloy of two is brass.
Now,since Zn is above Cu in reactivity series,therefore on treatment with dilute sulphuric acid,it will react,as shown:
Zn + dil H2SO4 ZnSO4 + H2O
Copper has a reddish brown appearence. So,it is confirmed.
