What is the charge on the hydronium ion?

Answer 1

The hydronium ions have a +1 charge - the formula is H3O+

Answer 2

Hydronium ion is a water molecule with an extra hydrogen ion attached to it. ( H2O + H+ → H3O+). It usually used to determine the acidity of a chemical compound.

When a compound is put into water solution, the more the hydronium ion is produced, the higher the acidity is.

EX: HCl(aq) + H2O(l) <----> Cl- + H3O+

The Hydrogen ion is transferred to water molecule.

A hydronium ion can also be represented as just a hydrogen ion (H+) in place of H3O+.
HCl(aq) → H+(aq) + Cl-(aq)

Answer 3

Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule.

Hydroxide ion, OH-, gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water.

Combining H3O+ + OH- makes 2 H2O. In other words, an acid and a base combine to neutralize each other as water.

Answer 4

The hydronium ion is a polyatomic ion that forms when an acid releases a proton (H+) to a water molecule. The formula is H3O+

Answer 5

+1
