Question

Each of the following reactions shows a solute dissolved in water. classify each solute as a strong electrolyte, a weak electrolyte, or a nonelectrolyte.

A(I) ---> A(aq)
Z(s) ---> Z(aq)

Answer 1

In order to classify solutes as strong electrolytes, weak electrolytes, or nonelectrolytes, we need to understand their behavior when dissolved in water. Substances that yield ions to a great extent are considered strong electrolytes, while those that yield only a small fraction of ions are weak electrolytes. Substances that do not yield ions are called nonelectrolytes.

Step-by-step explanation:

In order to classify each solute as a strong electrolyte, weak electrolyte, or nonelectrolyte, we need to understand the concept of electrolytes. When substances dissolve in water, they undergo a process that yields ions in solution. Substances that do not yield ions are called nonelectrolytes, while substances that yield ions to a great extent are known as strong electrolytes. Substances that only yield a small fraction of ions are considered weak electrolytes.

1. a. CH3CH₂CH₂OH: This is an organic compound and does not yield ions when dissolved. Therefore, it is a nonelectrolyte.
2. b. Ca(CH3CO2)2: This is a salt and it completely dissociates into ions when dissolved. Therefore, it is a strong electrolyte.
3. c. I₂: This compound is a covalent compound and does not yield ions when dissolved. Therefore, it is a nonelectrolyte.
4. d. KOH: This compound is a strong base and completely dissociates into ions when dissolved. Therefore, it is a strong electrolyte.
