Question

select the correct answer. which property of a substance can be determined using a ph indicator? a. acidity b. boiling point c. density d. electrical conductivity e. thermal conductivity

Explanation:

A pH indicator changes color depending on the acidity or alkalinity of a solution. It is specifically designed to show the pH level, which is a measure of acidity. Boiling point (related to phase change), density (mass per unit volume), electrical conductivity (ability to conduct electricity), and thermal conductivity (ability to conduct heat) are not determined by pH indicators.

Answer:

A. acidity
