Final answer:
Option d. weak base/accepts H+ from an acid is not correctly matched because a weak base typically accepts protons from water, not directly from an acid. The descriptions for the other options are correctly matched.
Step-by-step explanation:
The question asks which of the given options is not correctly matched with its description:
- a. weak acid/partially ionized
- b. salt/cation of an acid, anion of a base
- c. strong soluble base/soluble metal hydroxide
- d. weak base/accepts H+ from an acid
- e. strong electrolyte/strong acid, strong base, or soluble salt
The option that is not correctly matched is d. weak base/accepts H+ from an acid. A weak base does not accept H+ from an acid; instead, it is typically a substance that accepts hydrogen ions (protons) from water, increasing the OH-− concentration in solution. Therefore, the correct description for a weak base should focus on its ability to accept protons from water, not from an acid.
