Exothermic or Endothermic: Adding Concentrated Acid to Water
When concentrated acid is added to water, it is an exothermic process.
Explanation:
- Definition of Exothermic: An exothermic process is one that releases heat to its surroundings.
- Definition of Concentrated Acid: A concentrated acid is one that has a high acid concentration, meaning there are more acid molecules in a given volume of solution.
- Explanation of the Process: When concentrated acid is added to water, the acid molecules react with the water molecules to produce hydronium ions (H3O+) and heat. The heat produced is released to the surroundings, making this process exothermic.
Why is Adding Acid to Water Exothermic?
- Reason 1: When acid is added to water, the acid molecules dissociate into ions. This process releases energy in the form of heat.
- Reason 2: The reaction between acid and water is highly exothermic due to the strong attraction between the hydrogen ions (H+) in the acid and the oxygen atoms in the water molecules.
Precautions:
- Precaution 1: Always add acid to water, and not the other way around. This is because adding water to acid can cause a violent reaction due to the large amount of heat produced.
- Precaution 2: Wear protective gear, such as gloves and goggles, when handling concentrated acid to avoid any contact with the skin or eyes.
Overall, the process of adding concentrated acid to water is exothermic due to the energy released during the dissociation of acid molecules and the strong attraction between the hydrogen ions in the acid and the oxygen atoms in the water molecules. It is important to take precautions when handling concentrated acid to avoid any accidents.

Since heat is released during dilution of acid so it is exothermic
