2. What is the effect of temperature on the solubility of: i. Ammonium chloride ii. Calcium sulphate iii. Potassium nitrate iv. Sodium chloride
Answers
Answer:
The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
Answer:
Increasing the temperature result in an increase in the amount of ammonium chloride that dissolve in 10ml of water. Therefore, if the temperature is increased then the solubility of solids in a liquid.
The solubility of calcium sulfate increases thus when the temperature decreases. ... It is less common than for most of the salts whose dissolution reaction is endothermic (i.e., the reaction consumes heat: increase in Enthalpy: ΔH > 0) and whose solubility increases with temperature.
The solubility of all three solutes increases as temperature increases. the solubility of potassium nitrate increases the most from approximately 30 g per 100 g water to over 200 g per 100 g water.
Temperature dependence of NaCl is fairly flat, meaning that an increase in temperature has relatively little effect on the solubility of NaCl.
