Answer 2

Answer:

When an acid is dissolved in water we get an acidic solution. When a base dissolves in water it is an alkali and makes an alkaline solution. If a solution is neither acidic nor alkaline it is neutral. Pure water is neutral, and so is paraffin .

...

It is green in color for basic solution.

Explanation:

Litmus

Litmus indicator solution turns red in acidic solutions, blue in alkaline solutions, and purple in neutral solutions.

Litmus paper comes as red litmus paper and blue litmus paper. The table shows the colour changes it can make:

Red Litmus Blue Litmus

Acidic solution Stays red Turns red

Neutral solution Stays red Stays blue

Alkaline solution Turns blue Stays blue
