Question

What are the different types of acids?List four properties of acids.

Answer 1

Here is a list of ten common acids with chemical structures. Acids are compounds that dissociate in water to donate hydrogen ions/protons or to accept electrons.

1. Acetic Acid: Also known as: ethanoic acid, CH3COOH, AcOH.
Acetic acid is found in vinegar. This acid is most often found in liquid form. Pure acetic acid (glacial) crystallizes just below room temperature.
2. Boric Acid: Also known as: acidum boricum, hydrogen orthoborate
Boric acid may be used as a disinfectant or pesticide. It's usually found as a white crystalline powder.
3. Carbonic Acid: Also known as: aerial acid, acid of air, dihydrogen carbonate, kihydroxyketone.

Solutions of carbon dioxide in water (carbonated water) may be called carbonic acid. This is the only acid excreted by the lungs as a gas. Carbonic acid is a weak acid. It is responsible for dissolving limestone to produce geological features such as stalagmites and stalactites.

4. Citric Acid:

Also known as: 2-Hydroxy-1,2,3-propanetricarboxylic acid.

Citric acid is a weak organic acid that gets its name because it is a natural acid in citrus fruits. The chemical is an intermediate species in the citric acid cycle, which is key for aerobic metabolism. The acid is widely used as a flavoring and acidifier in food.
