What is the Mole Ratio between Calcium Chloride and Calcium Carbonate in the Following Reaction?

Understanding the Chemical Reaction

The given chemical reaction is a classic example of a single displacement reaction, where calcium carbonate (CaCO3) reacts with hydrochloric acid (HCl) to produce calcium chloride (CaCl2), water (H2O), and carbon dioxide (CO2). This reaction is commonly used in various industrial processes, including the production of calcium chloride and the treatment of wastewater.

Balanced Chemical Equation

The balanced chemical equation for the reaction is:

${ 2 \text{HCl} + \text{CaCO}_3 \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2 }$

Identifying the Mole Ratio

To determine the mole ratio between calcium chloride (CaCl2) and calcium carbonate (CaCO3), we need to analyze the balanced chemical equation. The mole ratio is the ratio of the number of moles of one substance to the number of moles of another substance in a chemical reaction.

Calculating the Mole Ratio

From the balanced chemical equation, we can see that 2 moles of HCl react with 1 mole of CaCO3 to produce 1 mole of CaCl2. This means that the mole ratio of CaCl2 to CaCO3 is 1:1.

Conclusion

In conclusion, the mole ratio between calcium chloride (CaCl2) and calcium carbonate (CaCO3) in the given reaction is 1:1. This means that for every 1 mole of CaCO3, 1 mole of CaCl2 is produced.
