Question

Select the chemical equation that most likely represents the reaction between the vinegar and the dolomite.

Answer 1

B. MgCO3 + 2HCH3COO -----> Mg(CH3COO)2 + CO2 + H2O

Answer 2

Answer: The reaction is given below.

Explanation:

Dolomite is a carbonate ore of calcium and magnesium. Its chemical formula is $CaMg(CO_3)_2$.

Another name of vinegar is acetic acid and its chemical formula is $CH_3COOH$

The reaction between vinegar and dolomite follows the equation:

$4CH_3COOH+CaMg(CO_3)_2\rightarrow Ca(CH_3COO)_2+Mg(CH_3COO)_2+2CO_2+H_2O$

By Stoichiometry of the reaction:

4 moles of acetic acid reacts with 1 mole of dolomite to produce 1 mole of calcium acetate, 1 mole of magnesium acetate, 2 moles of carbon dioxide and 1 mole of water.
