Degassed water was added (see Table 6), and the solution was stirred overnight. 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.
Thus, either the acidity or basicityconstant describes fully the protolysis (proton transfer) properties of an acid-base pair in water. The stronger the acidity of an acid, the weaker the basicityof its conjugate base, and vice versa. The product of the K. a • K. b. of a conjugate pair is equal to K. W.

This reaction indicates the amphoteric nature of water. It can act as an acid as well as a base. One water molecule donates electron whereas other water molecule accepts electron. The self-ionization of water is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H2O, deprotonates to become a hydroxide ion, OH−. The hydrogen nucleus, H+, immediately protonates another water molecule to form hydronium, H3O+. It is an example of autoprotolysis, and exemplifies the amphoteric nature 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.
…containing active metals is the protolysis (proton-transfer) reaction that takes place with very weak protonic acids, including water. Alcohols react in a manner similar to the reaction of water, and this provides a convenient way of introducing an alkoxide (OR) substituent into an organometallic compound.
Thus, either the acidity or basicityconstant describes fully the protolysis (proton transfer) properties of an acid-base pair in water. The stronger the acidity of an acid, the weaker the basicityof its conjugate base, and vice versa.
This is self ionization of water.Nov 22, 2019 Auto-protolysis is also called the self-ionization. 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). Significance: Ability of Water to act as an acid as well as base.

Alcohols react in a manner similar to the reaction of water, and this provides a convenient way of introducing an alkoxide (OR) substituent into an organometallic compound. 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. water shows its amphoteric nature due to autoprotolysis i.e.
2H2O → H3O + + OH- The significance of autoprotolysis of water is that water can act as amphoteric substance. Answered on: 2016/09/27 by ExamFear
A sample of drinking water was found to be severely contaminated with chloroform, CHCl 3, supposed to be carcinogenic in nature. The level of contamination was 15 ppm (by mass).
2 H2O (l) H3O+(aq) + OH- (aq) a. Calculate the enthalpy the equation for the reaction of the base with water; the equilibrium expression, K b, for the reaction; the equilibrium concentration of each species (molarity or Confused high school student here.
