which pair of substances would most likely result in the production of a solid when reacting with a base?\nlitmus and phenolphthalein\nsoluble metal salt and carbon dioxide\nacids and water\nhydrogen ions and soaps
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.
