Question

What is one way to test whether and unknown solution is acidic or basic

Answer 1

an acid is an ionic compound that produces positive hydrogen ions when dissolved in water and a bacis is an ionic compound that produces negative hydroxide ions when dissolved in water

Answer 2

Answer: By using litmus paper.

Explanation:

Litmus paper is an indicator which helps us to determine the solution as acidic or basic. These are of two types: red litmus paper and Blue litmus paper.

Red litmus paper is resistant to Acidic solution but it changes its color to blue when dipped in basic solution.

Blue litmus paper is resistant to Basic solution but it changes its color to red when dipped in acidic solution.

Hence, we can use litmus paper to test whether the unknown solution is acidic or basic.
