Question

Mcq When zinc poweder is added to acetic acid ? A.the mixture becomes warm B.a gas is evolved C.the colour of mixture becomes yellow D.a solid settles at the bottom

Answer 1

B. A gas is evolved

Explanation:

When an active metal reacts with a dilute non-oxyacid, hydrogen steam is typically liberated and a SOLUBLE metal salt is typically formed.

This is normally given by:

`"Metal"+"Dilute Non-Oxyacid"rarr"Salt"+"Hydrogen"`

Here, the reaction is:

`"Zn"(s)+2"CH"_3"COOH"(aq)rarr2"Zn(CH"_3"COO)"_3(aq)+"H"_2(g)uarr`,

or zinc plus acetic acid gives zinc acetate and hydrogen.
