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). (i) Express this in percent by mass. (ii) Determine the molality of chloroform in the water sample. Q:-What is meant by the term bond order? the protolysis (or the acid dissociation reaction) is used in practice to calculate the pK a value using the Equation (11) pK a ¼ logðK a Þ: (11) Protolysis is one of the most ubiquitous reactions that is involved in most chemical and biological processes, and as such, this reaction has long been the interest of a broad research community.

Protolysis of water

Auto-protolysis is the transfer of a proton between two of the same molecules. The auto-ionisation of water is one example of auto-protolysis. Kw K w is the equilibrium constant for this process: Kw K w = [H3O+][OH−] [ H 3 O +] [ OH −] U can like my Facebook page ie.

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.

Auto-protolysis of water means that two molecules of water react with each other through proton transfer, i.e., one acts as the acid and the other acts as a base. The molecule which accepts a proton is converted into ${{H}_{3}}$O+ while the other which donate a proton is converted into OH- ion. What is auto protolysis of water.

Water restoration is your best option t If you have hard water, you'll see some obvious signs in and around your home. Although a water softener is an investment, if you have hard water, it's usually a worthwhile expenditure to avoid common hard water issues. There are approximately 4.2 US cups of water in a liter.
