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. done
Answer
Answer:
B. Fizzing will occur because carbon dioxide is produced.
Explanation:
Step1: Acid - carbonate reaction
Acetic acid ($CH_3COOH$) reacts with magnesium carbonate ($MgCO_3$).
Step2: Chemical reaction equation
$MgCO_3 + 2CH_3COOH=(CH_3COO)_2Mg + H_2O+CO_2\uparrow$.
Step3: Observation due to gas production
The production of carbon - dioxide gas causes fizzing.
