When you mix baking soda with vinegar is the reaction endothermic or exothermic?

Try it and see. Does the beaker get warm or cool?

Or, try google.

When you mix baking soda (sodium bicarbonate, NaHCO3) with vinegar (acetic acid, CH3COOH), the reaction that takes place is an exothermic reaction. This means that the reaction releases heat energy into the surroundings. As the baking soda reacts with the vinegar, it produces carbon dioxide gas (CO2), water (H2O), and a salt called sodium acetate (CH3COONa). The release of heat energy in this reaction makes it exothermic.

The reaction between baking soda (sodium bicarbonate, NaHCO3) and vinegar (acetic acid, CH3COOH) is a classic example of an acid-base reaction, producing carbon dioxide gas (CO2), water (H2O), and a salt (sodium acetate, NaCH3COO). This reaction is exothermic, meaning it releases heat.

To understand why it is exothermic, we need to look at the reaction on a molecular level. When baking soda and vinegar are mixed, the following reaction occurs:

NaHCO3 + CH3COOH → CO2 + H2O + NaCH3COO

During this reaction, the bicarbonate ion (HCO3-) in baking soda reacts with the hydrogen ion (H+) in vinegar, forming carbon dioxide gas, water, and sodium acetate. This reaction releases energy in the form of heat.

To verify that the reaction is exothermic, you can perform a simple experiment. Mix a known amount of vinegar with baking soda in a container and measure the change in temperature using a thermometer. You will notice that the temperature of the mixture increases, indicating the release of heat energy.

Overall, the reaction between baking soda and vinegar is an exothermic reaction because it releases heat energy.
