Question

What does a solubility curve show?
(A) The relationship between temperature and the solubility of a substance.
(B) The relation between pressure and the solubility of a substance
(C) The relationship between type of solute and the solubility of a substance
(D) The relationship between type of solute and the solubility of a solvent
(E) The relationship between temperature and the solvent

Answer 1

A solubility curve is a data-based graph comparing the amount of solute that will dissolve in a given amount of solvent at various temperatures. The most typical solubility curves are graphed based solid and gaseous solutes dissolved in 100 grams of water

Complete step by step answer:
We have been asked about the solubility curve,
So, firstly we will talk about solubility,
Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.
Solubility Curve used to determine the mass of solute in 100 g (100 ml) of water at a given temperature,
The solubility curve helps us to predict which substance will crystallize out first from a solution containing two or more solutes. The solubility curve helps us to compare the solubilities of different substances at the same temperature. It brings the change in the solute composition substance.
From this we can say that the solubility shows the relationship between temperature and the solubility of a substance.
Therefore, option (A) is correct.

Note: Discontinuous solubility curve: The solubility curve which shows that the solubility increases or decreases irregularly with temperature is called the discontinuous solubility curve. These types of curves are given by hydrated salts like calcium chloride and copper sulphate pentahydrate.
