which of the following substances is insoluble in water a salt b stone c sugar d vinegar
Answer (1)
The correct answer is B. StoneExplanationSalt (A) is soluble because when mixed with water, it breaks into tiny particles and disappears.Sugar (C) also dissolves easily in water and creates a sweet solution.Vinegar (D) is a liquid that completely mixes with water since it’s already water-based.Stone (B) is not soluble because it’s a solid that stays the same even when soaked—it doesn’t break apart or disappear in water.Insoluble means a substance does not dissolve in water.
