how a chemical reaction between molecules of baking soda and molecules of citric acid could also have produced some new water molecules
Answers
Answer:The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
Explanation:
Some of the water generated in this process comes from the chemical reaction between the molecules of baking soda and molecules of citric acid.
When baking soda (sodium bicarbonate, NaHCO3) reacts with citric acid (C6H8O7), it produces carbon dioxide (CO2) gas, water (H2O), and a soluble salt called sodium citrate (Na3C6H5O7).
The chemical reaction can be represented as follows:
NaHCO3 + C6H8O7 → Na3C6H5O7 + CO2 + H2O
In this reaction, one molecule of baking soda reacts with one molecule of citric acid to produce one molecule of water along with carbon dioxide and sodium citrate.
The water molecule is formed by the combination of hydrogen ions (H+) from citric acid and bicarbonate ions (HCO3-) from baking soda.
The hydrogen ions and bicarbonate ions react to form carbonic acid (H2CO3), which then decomposes into carbon dioxide and water:
H+ + HCO3- → H2CO3
H2CO3 → CO2 + H2O
Therefore, some of the water produced in this reaction comes from the chemical reaction between the molecules of baking soda and molecules of citric acid, as hydrogen and bicarbonate ions combine to form carbonic acid, which then breaks down into carbon dioxide and water.
