what is the action of conc sulphuric acid on zn, Mg, Fe, cu ,H2S ?
Answers
Answer:
ANSWER
◼Concentrate sulphuric acid is also known as the king of acids and highly reactive and corrosive in nature .
◼According to properties of acid , when it reacts with a metal it loses gives a sulphate salt and hydrogen.
▶So, when it reacts with zinc it gives out zinc sulphateZnSO_4ZnSO

and hydrogen .
