7. Which of the following cannot be known by using a solubility curve? a. solubility of a substance at a particular temperature b. comparison of solubility of two solute in the same solution C.state of solute and solvent d. relation of temperature and solubility of a substance
Answers
Answer:
d answer is always right
The statement from the above-given options that cannot be proved using a solubility curve is:
(C.)state of solute and solvent
The explanation for the above answer is:
A solubility curve is a graphical representation determining the variation or change in the solubility of the given substance in a solvent or the solution concerning the temperature change.
Option(a): it is determined by the solubility curve
The solubility curve determines and helps us find the solubility for a given substance at a particular temperature although it keeps changing.
Option(b): it can also be known by the solubility curve
The solubility curve helps in the comparison of the solubility of two substances present in the same solution at a given temperature. It also helps in predicting which substance crystallizes first when two are present in the same solution.
Option(c):
The state of solute or solvent cannot be determined by the solubility curve.
Option(d): it can be known by the solubility curve
by definition the solubility curve determines the relation between temperature and solubility of a substance.
