Answer 2

Answer:

The colors obtained on a pH paper for highly acidic, basic, and neutral solutions are red, blue, and green respectively.

Explanation:

pH is a measure of hydrogen ion concentration in a solution. A pH paper is used to measure pH according to its color.

• Acidic: An acid is a substance that can give hydrogen ions in a solution. Acidic solutions have a pH lower than 7. Highly acidic solutions show red color on pH paper
• Basic: A base is a substance that can give hydroxide ions in a solution. Basic solutions have a pH greater than 7. Highly basic solutions show blue color on pH paper.
• Neutral solutions: A solution that is neither acidic nor basic is called a neutral solution. Neutral solutions have pH 7. It shows green color on pH paper.
