Let's evaluate each statement to determine which are true. Step 1: Evaluate statement A. "Acid-base indicators are used to determine whether an unknown solution is an acid, base, or salt." Acid-base indicators change color depending on the pH of the solution, allowing us to classify a solution as acidic, basic, or neutral (which would result from a salt solution). This statement is true. Step 2: Evaluate statement B. "Solution X + methyl orange = red, solution X is an acid." Methyl orange is an indicator that turns red in acidic solutions (typically below pH 3.1). Therefore, if solution X turns methyl orange red, it is an acid. This statement is true. Step 3: Evaluate statement C. "Solution Y + methyl orange = yellow, solution Y is a base." Methyl orange turns yellow in basic solutions (typically above pH 4.4). Therefore, if solution Y turns methyl orange yellow, it is a base. This statement is true. Step 4: Determine the correct option. Since statements A, B, and C are all true, the option that encompasses all of them is the correct answer. The final answer is D) All of these.
