Question

a meta M forms an oxide having the formula m2o3 . it dissolves both in dilute sulphuric acid and dilute sodium hydroxide solution. identify the metal and write equations for the chemical reactions involved.

we can store copper sulphate solution in a silver vessel but not silver nitrate solution in a copper vesse. explain why ?

Answer 1

Answer:

Explanation:it is Al203 (it is an amphoteric oxide)

Al2O3 + NaOH = NaAlO2 + H2O

Al2O3(s) + H2So4(aq) = Al2(So4)

in electrochemical series Cu is above Ag

Cu can reduce silver nitrate and can poison food

but silver cannot reduce copper sulphate

Answer 2

Answer:

Aluminum is the correct answer.
