Which of the following statements about the solubility of alkali metal hydroxides in water is correct? A) All alkali metal hydroxides are insoluble in water. B) Alkali metal hydroxides are only slightly soluble in water. C) Alkali metal hydroxides are equally soluble regardless of atomic number. D) Solubility increases with the atomic number of the alkali metal.
Understand the Problem
The question is asking us to determine the correct statement regarding the solubility of alkali metal hydroxides in water, focusing on their solubility characteristics based on atomic number.
Answer
Solubility increases with the atomic number of the alkali metal.
The final answer is D) Solubility increases with the atomic number of the alkali metal.
Answer for screen readers
The final answer is D) Solubility increases with the atomic number of the alkali metal.
More Information
Alkali metal hydroxides are known to be soluble in water, and the solubility increases as you move down the group, from lithium hydroxide to cesium hydroxide.
Tips
A common mistake is assuming that all metal hydroxides share similar solubility properties. However, alkali metals have distinctive trends due to their unique atomic structures.
