Comparing Strengths of Oxidants and Reductants
WebpH is a representation of hydrogen ion activity in a liquid. It is the negative logarithm of the number of hydrogen ions (in moles) per liter of liquid. Thus: 10 -11 moles of hydrogen ions in 1 liter of liquid = 11 pH. 10 -5.3 moles of hydrogen ions in 1 liter of liquid = 5.3 pH. Bromine is the third halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to those of fluorine, chlorine, and iodine, and tend to be intermediate between those of the two neighbouring halogens, chlorine, and iodine. Bromine has the electron configuration [Ar]4s 3d 4p , with the seven electrons in the fourth and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agen… how to stop a persistent cough at night
