A solution 'X' give orange colour when a drop of it falls on pH paper, while another solution 'Y' gives bluish colour when a drop of it falls on pH paper. What is the nature of both the solutoins? Determine the pH of solution 'X' and 'Y'?

Text Solution

Verified by Experts

Solution 'X' is acidic in nature as it turns into orange when a drop of it falls on a pH paper. It pH value will be in the orange of 3 to 5 and is moderately acidic.
Solution 'Y' is basic in nature as it turns into blue colour when a drop of it falls on a pH paper. Its pH value ranges from 8 to 11 and is moderately basic.
