Acidity (pH level) measures the amount of hydrogen in the mixture.
pH is the negative log of the hydrogen ion concentration.
so if a solution has a hydrogen concentration of 4.3x10-6moles/litre its pH is 5.37
Answer 2
The hydrogen we are talking about is hydogen ions, i.e. what cause acidity. pH stands for 'potential hydrogen'.

When the two Punches match, the solution is called neutral with a pH value of 7. Maximum H+ goes to pH 1. Maximum -OH [-1] goes to pH 14.

How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
What is 0.000001 what is the pH?
if 0.000001 is the hydrogen ion concentration the pH is 6
How does pH relate to hydrogen ion concentration?
pH = -log[H+]
Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
What is the measurement of hydrogen ion concentration?
A measurement of hydrogen ion concentration is pH, which equals-log[H+], which is the negative logarithm of the hydrogen ion concentration (actually activity, but that is usually ignored). This quantity can be measured with a hydrogen electrode (as found in a pH meter), which is a type of ion selective electrode.

What is the pH of soultion?
PH means negative logarithom of hydrogen ion concentration…so value of hydrogen ion concentration in solution is called the PH of solution.
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What is the pH of hydrogen ion is 100 times of hydroxide ion?
The pH of such a solution would be 6.
What is the difference between pH and hydrogen ion concentration?
The pH value of a particular solution is equivalent to -log[hydrogen ion concentration].
How does the concentration of hydrogen ions vary with pH?
pH is the negative log of the hydrogen ion concentration. So lowering pH from 5 to 4 means a ten times increase in hydrogen ion concentration. Increasing pH by 1 results in decreasing hydrogen ion concentration to 1/10th its former level.
What is the pH solution defined as what of the hydrogen ion concentration?
The pH is a measure of the activity of the ion H+ in a solution.
What is 0.000001 what is the pH?
if 0.000001 is the hydrogen ion concentration the pH is 6

What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
