To identify the liquids, the student can use the equilibrium reaction of sodium chloride. When Na Cl molecules are formed, they crystallize and dissolve in water, forming a solution of sodium and chloride ions. Adding sodium chloride in water will not have a chemical reaction. If the NaCl solution forms crystals and dissolves in the liquid, it means hydroxide ions are present, this will be the solution with the basic pH. However, if the NaCl solution forms crystals and dissolves, and the liquid contains added electrolytes such as Na+(aq), it means that the liquid is the sports drink because of the added electrolytes.

paraphrase this, make it flow better. More understandable.

Answer 1

To determine the liquids, the student can use the equilibrium reaction of sodium chloride. When sodium chloride molecules dissolve in water, they form a solution of sodium and chloride ions. If the NaCl solution dissolves and forms crystals in the liquid, it indicates the presence of hydroxide ions and a basic pH. However, if the NaCl solution dissolves and the liquid contains added electrolytes like Na+(aq), then it is likely the sports drink due to the electrolyte content.
