Best Answer

None of the above. Oxygen is an element, while acids and bases are compounds of more than one element. The degree of acidity or alkalinity is given as pH, which is a measure of the Hydrogen ion concentration in the solution. Oxygen by itself, being an element, has no hydrogen ion concentration, so is none of those things. Neither, in that context of pH, is it neutral.

The peroxide ion is a base.

Neither. Strictly speaking it is a very weak base. A Magnesium Nitrate solution is neutral with a pH of 7.0. Salts of strong acids are neutral. Magnesium Nitrate is salt of Nitric acid which is very strong acid.

There is no conjugate) base coupled to bromide, Br-, because this Br- can NOT donate (by protolysing) a proton (H+) in water.However Br- itself is the very, very weakest base of the (very, very) strong conjugate acid HBr.This is the only possible conjugate acid/base pair:HBr/Br-
