- This characteristic allows it to donate two protons, making it a dibasic acid.
- Phosphorous acid is often used in the preparation of phosphite salts, which are important in agriculture and industry.
Additional Information
- Phosphoric Acid (H3PO4)
- Phosphoric acid is a tribasic acid with three hydrogen atoms available for donation.
- It is widely used in the food industry, especially in cola beverages.
- In agriculture, it is used as a fertilizer component.
- Boric Acid (H3BO3)
- Boric acid is a weak monobasic acid.
- It is commonly used as an antiseptic, insecticide, and flame retardant.
- Arsenic Acid (H3AsO4)
- Arsenic acid is a tribasic acid similar to phosphoric acid.
- It is used in the manufacture of arsenate wood preservatives.
- Acidity
- Acidity refers to the ability of a substance to donate hydrogen ions (H+) in an aqueous solution.
- Acids are classified based on the number of hydrogen ions they can donate (monobasic, dibasic, tribasic).
