Answer 1

Answer:

Because lemon juice is acidic, it makes blue litmus paper turn red. Because soapy water is alkaline, it turns red litmus paper blue.

Answer 2

If lemon juice is tested with red litmus paper, there is no change occur in red litmus.

Explanation:

• If lemon juice is treated with red litmus, then there will be no change observed.
• This is because the lemon water is already acidic in nature. So treating it with red litmus does not change the color of the paper.
• When we treat lemon juice with blue litmus it changes blue litmus into red litmus.
• This is because blue litmus is basic in nature so it turns red as lemon juice is acidic in nature.
