A drop of vinegar ( a weak acid ) is placed on a sample of each of the materials below. Which will show the most active reaction? A. glass
B. marble
C. copper
D. steel

Answers

Answer 1
Answer:

Answer: Option (B) is the correct answer.

Explanation:

Marble is also known as calcium carbonate and its chemical formula is CaCO_(3).

When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.

The reaction is as follows.

    CaCO_(3) + CH_(3)COOH \rightarrow Ca(CH_(3)COOH)_(2) + H_(2)O + CO_(2)

Whereas vinegar being a weak acid will not react with glass, copper and steel.
