Which pair forms an aqueous solution?
Answer and explanation
Correct answer: Salt and water
An aqueous solution is specifically a solution in which water acts as the solvent. Salt dissolves in water and produces salt water, so this pair forms an aqueous solution. Copper-zinc is associated with an alloy, nitrogen-oxygen forms a gaseous mixture, and hydrogen in palladium is a gas-in-solid example rather than an aqueous solution.
