The degree of dissociation of week electrolyte increases as________________?
Correct answer: C. Dilution increases
- A. Pressure increases
- B. Dilution decreases
- C. Dilution increases
- D. None
Explanation
Dilution increases the degree of dissociation of a weak electrolyte because the lower concentration reduces the tendency of oppositely charged ions to recombine. Thus more molecules dissociate into ions. The likely wrong choice is dilution decreases, which reverses the effect of dilution on weak electrolytes.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
