Answers
Step-by-step explanation:
A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH of the solution can be determined visually. Hence, a pH indicator is a chemical detector for hydronium ions or hydrogen ions in the Arrhenius modelEconomics is the social science that studies how people interact with value; in particular, the production, distribution, and consumption of goods and services. Economics focuses on the behaviour and interactions of economic agents and how economies work
