Question

Calcite (the main mineral in limestone) is made of calcium carbonate (caco3). dolomite, a related mineral, is made of magnesium carbonate (mgco3). what happens if a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite? there is no way to predict what will happen. fizzing will occur because carbon dioxide is produced. no reaction will occur because dolomite contains no calcium.

Answer 1

If a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite, fizzing will occur because carbon dioxide is produced.

Why Carbon dioxide show effervescence?

Effervescence observes whenever any gas tried to escape out from an aqueous solution, that's why CO₂ show effervescence.

Reaction between dolomite and acetic acid will be represented as:

MgCO₃ + 2CH₃COOH → CO₂ + H₂O + Mg(CH₃COO)₂

From the above reaction it is clear that carbon dixide gas is produced by showing the effervescence and fizzing behavior.

Hence, option (2) is correct.
