Sagot :
The pH can be defined as the measure of the acidity or the basicity of the solution. The ratio of hydrogen ion concentration and hydroxide ion concentration at pH 7 is 1.
What is hydrogen ion concentration?
The hydrogen ion concentration can be given as the amount of hydrogen percent in the sample solution.
The pH has been the negative logarithmic value measurement of the hydrogen ion in the sample. The sum of the hydrogen ion and the hydroxide ion in the sample has been a constant 14.
[tex]\rm pH+pOH=14[/tex]
The pH can be given as:
[tex]\rm pH=-log[H^+][/tex]
At pH 7 neutral pH the concentration of Hydrogen ion and hydroxide are equal i.e.
[tex]\rm 7=-log[H^+]\\H^+=10^{-7}\;M[/tex]
The hydroxide ion concentration has been given as:
[tex]\rm pOH=-log[OH^-]\\7=-log[OH^-]\\OH^-=10^{-7}\;M[/tex]
The concentration of hydrogen and hydroxide are equal at pH 7. Thus, the ratio of the concentration has been 1.
This states the sample to be neutral.
