a metal x form a salt xso4 form a clean solutions in water which react with Naoh solution so form blue precipitate y .metal x is used making electric wire and alloy like brass.what do think metal x could be?

Since this is homework.. and the site rules require you to attempt it first... what do you think it is and why?

What is the charge of the SO4 ions, which metals have a matching opposite charge? What are the components of brass? Of those components which have a higher reactivity than Na?

Good luck.
