is directly related to the ideal gas law.
The ideal gas law states that:
. Rewriting this gives:
. R is the universal gas constant, so its value is fixed. For a given sample, n is the number of moles of the gas, so its value would be fixed too. This means that the value of 
would be a fixed constant as well. Therefore, whatever the initial value 
is, it should be equal to the final value

The pH scale for acidity is defined by pH = − log₁₀[H⁺] where [H⁺] is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pH of 2.55. Find the hydrogen ion concentration.
Answer: -
0.003 M
Explanation: -
pH = − log₁₀[H⁺]
Thus the hydrogen ion concentration [H⁺] =
=
= 0.003 M
