Chemistry
pH Calculator
Convert hydrogen ion concentration [H⁺] in mol/L into a pH value using pH = −log₁₀[H⁺]. The standard measure of acidity used in chemistry, biology, environmental science, and any application where solution acidity matters.

Chemistry
Ideal Gas Law Calculator
Solve the ideal gas equation PV = nRT for whichever variable you need — pressure, volume, temperature, or moles — given the other three. The foundational equation for any gas-phase chemistry or thermodynamics problem at moderate temperatures and pressures.
