Answer

Answer:

B. soluble metal salt and carbon dioxide

Explanation:

Step1: Analyze option A

Litmus and phenolphthalein are indicators, not substances that form a solid with a base.

Step2: Analyze option B

A soluble metal - salt can react with carbon dioxide in the presence of a base to form a metal carbonate precipitate (a solid). For example, calcium hydroxide (a base) reacts with carbon dioxide and a soluble calcium - containing salt to form calcium carbonate solid.

Step3: Analyze option C

Acids and water do not form a solid when reacting with a base. The reaction between an acid and a base is a neutralization reaction, usually resulting in a salt and water.

Step4: Analyze option D

Hydrogen ions and soaps react to form fatty acids, not a solid in the context of reacting with a base.
