Question

A. Paint
B. Medicine
C. Gold
D. Cleaning agent

Answer

The correct answer is Gold. It matches formulation because the evidence is designed mixture composition and the expected result is useful product properties.

Explanation

The correct option is Gold. Use this as an exam check: if the observation is not useful product properties, the conclusion about formulation is not properly supported. Other options are weaker when they confuse gas tests, flame colours, ion-test precipitates, chromatography evidence, or pure-substance/formulation wording.

Common mistake

Misidentifying Formulations

Students often confuse formulations with pure substances, thinking that all mixtures are formulations.

Remember that a formulation is a specific type of mixture designed for a useful purpose, while a pure substance is a single element or compound.
