An indicator is a substance which changes its color in the presence of acid or base. It is indicative of acid and base in the solution. An indicator is used in chemical laboratory. An indicator is used in the titration process of the solutions to indicate the completion of the acid-base related reactions.
Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.
