This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

α-Aminobutyric acid is one of the three isomers of aminobutyric acid. The two other are the neurotransmitter γ-Aminobutyric acid (GABA) and β-Aminobutyric acid (BABA) which is known for inducing plant disease resistance. The conjugate base of α-aminobutyric acid is the carboxylate α-aminobutyrate. This amino acid has been detected in ...

Reduction 4H + + 4e − → 2H 2 E° = 0.00 V vs. NHE Overall 2H 2 O → 2H 2 + O 2 E°cell = +1.23 V; ΔG = 475 kJ/mol . Water splitting can be done at higher pH values as well however the standard potentials will vary according to the Nernst equation and therefore shift by -59 mV for each pH unit increase. However, the total cell potential ...
In thermolysis, water molecules split into hydrogen and oxygen. For example, at 2,200 °C (2,470 K; 3,990 °F) about three percent of all H 2 O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H 2, O, O 2, and OH. Other reaction products like H 2 O 2 or HO 2 remain minor. At the very high temperature of 3,000 ...

pK a H 2 CO 3 is the negative logarithm (base 10) of the acid dissociation constant of carbonic acid. It is equal to 6.1. [HCO − 3] is the concentration of bicarbonate in the blood [H 2 CO 3] is the concentration of carbonic acid in the blood; When describing arterial blood gas, the Henderson–Hasselbalch equation is usually quoted in terms ...
