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⁻

∙ 14y agoWater "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.

∙ 11y agoAutoionisation 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

How Does dirty Water Become Cleaned?
The answer depends on what is meant by dirty water. The treatment depends on the contaminant.
What is meant by a hydrophobic amino acid how does it behave around water?
A "hydrophobic" amino acid is an acid that "fears" water. When in contact with water, the hydrophobic amino acid will cause that section of protein to stay away from water.
What is meant by drift in a KF titration?
drift means gram eqv. of water removed by K.F. in Iodometric titration
What causes hot water heater in my home to give off fumes?
Firstly a water heater is a concealed unit and all joints are meant to be leak proof. Sounds like there is a leak somewhere in the water heater. Get a plumber to investigate and fix where necessary.
Can you emulsifier instead of surfactant?
Emulsion two types.1.Oil in water 2.water in oil.-- both will increases their viscosity. surfactant meant : De-emulsification which is quite opposite to emulsifier agent.surfactant decrease viscosity.
