Molecules on an acid–base indicator react chemically with ions in a solution, causing the indicator to change color. which ions in the solution cause this reaction? oxygen ions water ions hydrogen ions nitrogen ions

The correct answer is hydrogen ions.

Explanation:

Acid-base indicator is used to detect the pH of the solution.

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

The equation representing the reaction between hydrogen ions and acid-base indicator follows:

Hence, the correct answer is hydrogen ions.

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

the ratio of the conjugate base to the acid required to attain the desired ph.
