A water ionizer (also known as an alkaline ionizer) is a home appliance which claims to raise the pH of drinking water by using electrolysis to separate the incoming water stream into acidic and alkaline components. [1] [2] [3] The treated water is called alkaline water.
Alkaline water is water that has a higher pH level than normal drinking water (between 7.5 and 9 for alkaline water versus 7 for normal drinking water). Alkaline water may come from springs or ...
Pure water has a charge carrier density similar to semiconductors [12] [page needed] since it has a low autoionization, K w = 1.0×10 −14 at room temperature and thus pure water conducts current poorly, 0.055 μS/cm. [13] Unless a large potential is applied to increase the autoionization of water, electrolysis of pure water proceeds slowly ...
Typically, Nickel based metals are used as the electrodes for alkaline water electrolysis. [15] Considering pure metals, Ni is the least active non-noble metal. [ 16 ] The high price of good noble metal electrocatalysts such as platinum group metals and their dissolution during the oxygen evolution [ 17 ] is a drawback.
The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.
A Piper diagram is a graphic procedure proposed by Arthur M. Piper in 1944 for presenting water chemistry data to help in understanding the sources of the dissolved constituent salts in water. This procedure is based on the premise that cations and anions in water are in such amounts to assure the electroneutrality of the dissolved salts, in ...
In the carbonate system the bicarbonate ions [HCO − 3] and the carbonate ions [CO 2− 3] have become converted to carbonic acid [H 2 CO 3] at this pH. This pH is also called the CO 2 equivalence point where the major component in water is dissolved CO 2 which is converted to H 2 CO 3 in an aqueous solution. There are no strong acids or bases ...
