Respuesta :
The pH is the measure of hydrogen ion concentration in a solution. The hydrogen ion concentration at pH 1.25 is [tex]\rm\bold{ 5\;\times 10^{-2}\;M}[/tex].
How to calculate hydrogen concentration?
The pH is the negative logarithmic value of the hydrogen ion concentration in the sample.
The pH can be expressed as:
[tex]\rm pH=-log[H^+][/tex]
The hydrogen ion concentration can be given as:
[tex]\rm [H^+]=10^{-pH}[/tex]
The given pH is 1.25 The hydrogen ion concentration is given as:
[tex]\rm [H^+]=10^{-1.25}\\H^+=0.05\;M\\H^+=5\;\times\;10^-^2\;M[/tex]
The hydrogen ion concentration in the solution is [tex]\rm 5\;\times\;10^{-2}\;M[/tex].
