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.
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.
PH is the negative logarithm of the?
hydrogen
What happens to the hydrogen ion concentration as you decrease the pH?
Hydrogen ion concentration increases.
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 the PH?
negative logarithm of hydrogen ion concentration
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.
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.
Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
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 the expansion for pH?
pH=potential of HydrogenIt is a negative logarithm to the base 10 of hydrogen ion concentration.For example the concentration of hydrogen ions in water is 1.0 x 10-7 g ions/litre.This is expressed as-log10(1.0 x 10-7)=7Water has a pH value of 7.
Is a pH element or compound?
Neither - its a measure of hydrogen ion concentration.
What is the pH of an aqueous solution with a H plus concentration of 1 X 10-3 M?
3: The negative of the logarithm (base 10) of the concentration. The logarithm of 1 is 0 and the logarithm of 10-3 is -3; the logarithm of their product is the sum of their individual logarithms, -3 in this instance, and the negative of -3 is +3.
What value is ued to express the acidity or bacity of a solution called?
The acidity or basicity are expressed by pH (the negative logarithm of the activity of hydronium ion).
