Is HCl and acid or base?
If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid.Strong and Weak Acids. Acids Bases HCl LiOH HBr NaOH HI KOH HNO 3 RbOH.

What is the name for h2so3?
Is h2so4 a salt?
Sulfuric acid has its two hydrogen atoms bonded to oxygen, ionizes in two stages, and is a strong diprotic acid. Because it is a diprotic acid, H2SO4 forms two series of salts: hydrogen sulfates, HSO4−, and sulfates, SO42−.

Is CH3COO an acid or base?
CH3COOH is a weak acid and dissociates partially in solution (as indicated with reversible arrow) to form H+ and CH3COO- ions. Since this is a reversible process, CH3COO- can accept H+ to form back CH3COOH. Therefore the nature of CH3COO- is basic and we call CH3COO- the conjugate base of CH3COOH.
