Question

Magnesium oxide was added to dilute HCl and magnesium oxide was a added to dilute NaOH.​

Answer 1

Answer:

Magnesium oxide is a base. when base reacts with an acid, it forms salt and water.This reaction is known as neutralisation reaction.

MgO(s)+2HCl(l)=MgCl

2

(aq)+H

2

0(l)

MgO doesnot react with NaOH. As NaOH is a base and bases react only with oxides of non-metal to form salt and water because oxides of non-metals are said to be acidic in nature so neutralization reaction take place. But MgO is a oxide of metal so, reaction is not possible.

Answer 2

Answer:

1. Magnesium oxide dissolves in dilute HCI. However,in dilute NaOH solution, magnesium oxide remains as it is.
2. Magnesium oxide is base. When magnesium oxide is added ti dillute HCI, an acid-base neutralization reaction takes place forming magnesium chloride and water.
3. 2HCL+MgO➡️MgCl2+H2O. When magnesium oxide is added to dilute NaOH, no such reaction occurs.
