Sugar becomes invisible after dissolving in water but the solution remains sweet. What is the correct reason?
Answer and explanation
Correct answer: Sugar particles spread uniformly in water
The governing concept is dissolution as a physical change and the uniform distribution of particles. Sugar is not destroyed; its particles separate from one another and spread among the water particles, becoming too small and dispersed to see individually. Because the sugar particles and their taste-producing properties remain, the solution is sweet. Water does not transform into sugar, and solutions can have many tastes, so B is the only scientifically correct explanation.
