Question
Which of the following substance is not dissolved in the water?
- Salt
- Sugar
- Soda
- Sand
Hint:
Sand
The correct answer is: Sand
- Baking soda, also known as sodium bicarbonate, dissolves quickly in both hot and cold water. However, if the water in its solution evaporates, this chemical will totally recover without alteration.
- Water does not dissolve sand. When put to water, it suspends and gradually settles. As a result, it is insoluble in water.
- sugar and salt particles dissolves completely in water.
