pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution. For example, for a solution with a hydrogen ion activity of 5×10 (at that level, this is essentially the number of moles of hydrogen ions per litre of solution) the argument of the logarithm is 1/(5×10 ) = 2×10 ; thus such a solution has a pH o… WebMar 25, 2024 · Structured water, sometimes called magnetized or hexagonal water, refers to water with a structure that has supposedly been altered to form a hexagonal cluster.
