Does the mass fraction of solute change when saturated lime is added to a small amount of lime?
If the temperature is cooled before the reaction, the mass fraction is the same as before.
Calcium hydroxide is slightly soluble substance solution, because the whole process is always related to a saturated solution, mass fraction and solute solubility in saturated solution, and the effect of solubility factor is temperature, so the key to the change of temperature. Quicklime reacts with water to produce a large amount of heat and rise in temperature.
However, the higher the temperature, the lower the solubility of calcium hydroxide, so the mass fraction of the first small, until the temperature is cooled, and then become larger.
