What is meant by autoionisation of water?

Answer 1

In the self-ionization of water, two water molecules produce a hydronium ion and a hydroxide ion by transfer of a proton. The equation: H₂O + H₂O H₃O⁺ + OH⁻

Answer 2

Water "splits" like this: H2O => H+ + OH- As water molecules are actually being "pulled apart" by other water molecules, we understand that one water molecule comes away with the H+ ion making a hydronium ion. The hydroxide ion, or OH- ion, is left in a "free" state. We might see the equation for this reversible reaction written like this: 2 H2O (l) <=> H3O+ (aq) + OH− (aq) This is the self-ionization of water. It's always happening in liquid water. Some molecules of water are being pulled apart (by other water molecules), and some ions are getting back together. This is happening in equilibrium for the temperature and pressure of the water that is being investigated. A link can be found below to check facts and learn more.

Answer 3

Autoionisation is a chemical process that occurs in water where dissociation occurs and a dynamic equilibrium is established

H2O <-> H+ (aq) + OH-(aq)

The equilibrium concentration of H+ in pure water at 250C is 10-7 mol

corresponding to a pH of 7

Answer 4

Autoionization of water refers to the process where water molecules can spontaneously transfer a proton between them, forming hydronium ions (H3O+) and hydroxide ions (OH-) in small amounts. This equilibrium reaction occurs in pure water, contributing to the slight conductivity and pH of water.

Answer 5

In the self-ionization of water, two water molecules produce a hydronium ion and a hydroxide ion by transfer of a proton. The equation: H₂O + H₂O H₃O⁺ + OH⁻

Answer 6

hydronium ion and the hydroxide ion

h2o + h2o <--> h3o+ + oh-

Answer 7

H20 + H20 = H30(positive) + OH(negative)

Answer 8

OH- and H+
