The terms dissolution, crystallization, dynamic equilibrium and saturated solution are defined respectively, as
(A) no more solute can be dissolved in the solution at a given temperature and pressure
(B) some solute dissolves and its concentration increases in solution.
(C) some solute particles in solution collide with the solid solute particles and get separated out of solution.
(D) number of solute particles going into solution will be equal to the solute particles separating out of the solution
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (B), (C), (D), (A)
Dissolution — (B)
Crystallization — (C)
Dynamic equilibrium — (D)
Saturated solution — (A)
Shortcut: Dissolution is (B) and the saturated solution is (A), so the order starts with (B) and ends with (A); only Option (4) does both.
