Activity 2.6 correct answers -The meaning of Solubility
1. They dissolved in the solvent.
2. Maximum amount of solute is dissolved when the solvent can no longer dissolve more of the solute (the excess
solute is visible in the test tube)
3. They dissolved. Because the temperature increased, the solubility of the solid solute increased so more of the solute
can then be dissolved in the solvent.
4. Some of it slowly dissolved, some of it didn’t dissolve. (low solubility due to lower temperature)
5. Solubility is the maximum amount of solute that can be dissolved in a quantity of solvent at a specific temperature.
Activity 2.7 correct answers Factors affecting the solubility of a substance
1. Among the three solutes, only naphthalene didn’t dissolve in water. Still, the others dissolved easily.
2. Salt dissolved in water
3. Among the solvents, oil dissolved in kerosene.
4. As the liquid cools, the dissolved solute (sodium bicarbonate) slowly solidified and settled at the bottom of the test
tube
5. Particle Size, Nature of Solute and Solvent, Temperature
