Which formulation forms a true solution when mixed with water?

Which formulation forms a true solution when mixed with water?

• A. Forms true solution when mixed with water
• B. Clear solution with emulsifiers to be diluted in water
• C. A dry granule
• D. A gas

Answer: (A)

A true solution forms when the solute dissolves completely in the solvent, yielding a uniform, single-phase mixture with no visible particles. The correct choice describes a formulation that forms a true solution when mixed with water, which means the active ingredient dissolves completely and blends evenly with the water. This contrasts with a dry granule, which would stay as solid particles until it fully dissolves (and might not do so immediately), a gas that may or may not fully dissolve depending on conditions, or an emulsion that remains a mixture of droplets of one liquid dispersed in another rather than a true solution. So the option indicating complete dissolution in water aligns with the definition of a true solution.
