WebMay 6, 2024 · pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water). Typically, values of pH range from 0 to 14, although very strong acids may have a negative pH, while very strong bases may have a pH exceeding 14. 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… did bangladesh used to be pakistan https://deadmold.com
