Question

Mega got a magnesium ribbon from the science lab C1 it took the white as and mix it in water then she tasted the solution with the Litmus Paper she was surprised to see the colour change she assumed that the Ash is basic in nature
1. what does the white ash refers to in this experiment?
2. what is the colour change of the litmus paper?.
3. which chemical property does it verify ​

Answer 1

Answer:

a) White ash is magnesium oxide.

b) Blue to red

c) It is acidic in nature

Explanation:

Answer 2

The answers to the given questions are as follows:

1. The white ash refers to magnesium oxide in this experiment.

2. The colour change of the litmus paper is - from red to blue.

Magnesium oxide reacts with water to give magnesium hydroxide. Magnesium hydroxide produced in this chemical reaction is alkaline in nature.

$MgO+H_{2}O \rightarrow Mg(OH)_{2}$

Preparing a solution of magnesium oxide will form magnesium hydroxide. Therefore, when it is tested with red litmus, its colour turns to blue while there's no change on blue litmus paper.

3. It verifies the following chemical property - Bases turn red litmus blue while there is no change on blue litmus paper.
