pH scale is a measure of the amount of a particle called [J] in the aqueous solutions. A solution of pH 7 contains [K] times more this particle than one of pH 9.
Question
pH scale is a measure of the amount of a particle called [J] in the aqueous solutions. A solution of pH 7 contains [K] times more this particle than one of pH 9.
Solution
The pH scale is a measure of the concentration of hydrogen ions (H+) in a solution. The scale ranges from 0 to 14. A pH of 7 is considered neutral, such as pure water. If the pH is less than 7, the solution is acidic, and if it's greater than 7, the solution is basic or alkaline.
The pH scale is logarithmic, meaning each step represents a tenfold difference in ion concentration. So, a solution with a pH of 7 has 10^2 (or 100) times more hydrogen ions than a solution with a pH of 9.
So, in the context of your question, [J] refers to hydrogen ions (H+) and [K] refers to 100.
