On Phase Behaviours in Lipid/Polymer/Solvent/Water Systems and their and polyelectrolyte-amphiphilic druginteraction in protolytic solvent medium.
Upon addition of an excess (20 equiv.) of degassed water, the solution turned brown after a few minutes, whereupon a black solid precipitated. The solvent was removed in vacuo, and the remaining solid was analyzed. What do you understand by the term ‘auto protolysis of water’? What is its significance?

Multiwavelength spectrophotometric determination of protolytic constants of 4-(2-pyridylazo)resorcinol (PAR) in binary dioxane + water mixtures. A. Rouhollahi
Auto-protolysis of water indicates its amphoteric nature i.e., its ability to act as an acid as well as a base. The acid-base reaction can be written as: Molar absorption spectrum of hydrogen peroxide in water, overlayed with the emission spectra (arbitrary units) of typical low- and medium-pressure mercury vapor lamps. [45] Once initiated, a chain radical mechanism involving conversion between hydroxyl radical and HO 2 • , while consuming H 2 O 2 occurs (reactions [ 46 ] and [ 47 ]), propagating the radical reaction ( Lunak and Sedlak, 1992 ). For example water undergoes self ionization as shown below.
Protolysis of water Here we see the chemical reaction in which one water molecule steals a proton from another: H 2 O + H 2 O → OH – + H 3 O +. The stolen proton is positive and the electron left behind is negative. They make you write H 3 O +, the “hydronium ion” in first-semester chemistry, but everybody else gets to write H 2 O → OH – + H +, as if the proton had just gotten
Auto-protolysis of water is a reaction in which self-ionization of water molecules takes place to produce hydronium ion (H3O+) and hydroxide ion (-OH).
What is significance?

The reaction involved can be represented as: Auto-protolysis of water indicates its amphoteric nature i.e., its ability to act as an acid as well as a base. Thus, either the acidity or basicityconstant describes fully the protolysis (proton transfer) properties of an acid-base pair in water.

Protons (H+ ions) from water protolysis 1.0*10-7 mol/L: It is a very very small part of the 55.6 mol water in that litre but it's why pH of water is 7.0!H2O --> H+ + OH-
the Hydronium Ion - conjugate acid the hydroxide ion - conjugate base Auto-protolysis of water. Auto-protolysis of water means its self-ionisation.

Self-ionisation of water can be represented as:The significance of auto-protolysis.
This reaction is also known as the auto-ionisation of water and the ions formed are a conjugate acid and base pair of water: Auto-protolysis (self-ionization) of water is a chemical reaction in which two water molecules react to produce a hydroxide ion (OH -) and a hydronium ion (H3O+). The reaction involved can be represented as: Auto-protolysis of water indicates its amphoteric nature i.e., its ability to act as an acid as well as a base.
