Is h2so4 a weak acid?

Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent. Acetic acid is stronger than carbonic acid, and so on….Strong and Weak Acids and Acid Ionization Constant.

Acid Conjugate Base
H2SO4 (sulfuric acid) HSO4− (hydrogen sulfate ion)
HNO3 (nitric acid) NO3− (nitrate ion)
Weak Acids

How is nitrous acid written in aqueous solution?

Gaseous nitrous acid, which is rarely encountered, decomposes into nitrogen dioxide, nitric oxide, and water: 2 HNO2 → NO2 + NO + H2O. Nitrogen dioxide disproportionates into nitric acid and nitrous acid in aqueous solution: 2 HNO2 + O2 → 2 HNO.

Is nitrite acidic or basic?

Both nitrogen and oxygen atoms carry a lone pair of electrons. Therefore, the nitrite ion is a Lewis base.

Is HNO2 soluble in water?

How is hydrogen fluoride and fluorine chemically related?

Fluorides, hydrogen fluoride, and fluorine are chemically related. Fluorine is a naturally-occurring, pale yellow-green gas with a sharp odor. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids.

What are the signs and symptoms of fluorine exposure?

First Aid. Warning: Fluorine is a corrosive gas and may be converted to hydrofluoric acid in the lungs and on other moist tissue. Signs and Symptoms of Fluorine Exposure: Signs and symptoms of acute exposure to fluorine include coughing, choking, and chills. Eye, nose, skin, and respiratory irritation may occur.

What is the atomic number 9 of fluorine?

Fluorine is a chemical element with symbol F and atomic number 9. Classified as a halogen, Fluorine is a gas at room temperature.

What happens to fluoride when it is dissolved in water?

Fluorine is a naturally-occurring, pale yellow-green gas with a sharp odor. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids. Sodium fluoride dissolves easily in water, but calcium fluoride does not. Fluorine also combines with hydrogen to make hydrogen fluoride, a colorless gas.
