Change in color of black tea on adding lemon juice in it is which type of change and give reason gow

Answer 1

On the pH scale, the difference between adjacent numbers represents a tenfold difference in acidity. For instance, a pH of 5 is 10 times more acidic than a pH of 6 and 100 times more acidic than a pH of 7.

Because they contain a high amount of citric acid, lemons have an acidic pH.

Lemon juice has a pH falling between 2 and 3, which makes it 10,000–100,000 times more acidic than water.
