Examine the statement.
Substances dissolve through three processes:
I. ionization
II. dissociation
III. dispersion
Which of the answer choices correctly lists the dissolving processes that change the identity of a substance?
I and II
II and III
I,II and III
I and III
I
The answer to this problem is going to be 1 and three letter D.
is it B
To determine the correct answer, we need to understand the processes of ionization, dissociation, and dispersion and how they relate to changing the identity of a substance.
Ionization is the process by which a compound breaks into ions when dissolved in a solvent. This means that the compound dissociates into its constituent ions. Dissociation, on the other hand, refers specifically to the separation of ions when a compound dissolves. In this case, the compound originally exists as ions, which separate from each other in the solvent.
Dispersion is a process that involves the dispersion of molecules or particles throughout a solvent. This process does not involve the formation or separation of ions.
Given this information, we can determine that the dissolving process that changes the identity of a substance occurs when the compound undergoes ionization or dissociation. Option I states that only ionization is a process that changes the identity of a substance, while option II only includes dissociation. Option III includes both ionization and dissociation, so it is a valid combination.
Therefore, the correct answer is: I, II, and III
That isn't my choice.
Define ionization. Does that change the identity of the substance?
Define dissociation. Does that change the identity of the substance?
Define dispersion. Does that change the identity of the substance?
If you will define those three terms and see which one(s) change the identity of the material you will have the answer.
