Calculators

Calculates the mass of a substance deposited or liberated during electrolysis, based on Faraday's laws of electrolysis.

Calculates the entropy change for ideal gases under isothermal conditions and for chemical reactions using the Gibbs free energy formula.

Calculates the vapor pressure of water at a given temperature using various empirical formulas. The calculator provides results from the Antoine equation, the August equation, the Tetens equation, the Rankine equation, and the Clausius-Clapeyron equation. Note that these formulas are approximations and may have limitations in accuracy depending on the temperature range.

Calculates the vapor pressure of a substance at a given temperature using the Clausius-Clapeyron equation. This calculator helps explore phase transitions and thermodynamics.

Calculates the volume or number of moles of a gas at Standard Temperature and Pressure (STP). STP is defined as 0°C (273.15 K) and 1 atm pressure. This calculator uses the ideal gas law to perform these calculations.

Calculates the freezing point depression of a solution using the colligative properties formula. This calculator determines the change in freezing point when a nonvolatile solute is added to a solvent.

Calculates the Gibbs Free Energy (ΔG) of a reaction to determine its spontaneity. A negative ΔG indicates a spontaneous reaction, a positive ΔG indicates a non-spontaneous reaction, and a ΔG of zero indicates equilibrium.

Calculates the reaction quotient (Q) to determine the direction a reversible reaction will shift to reach equilibrium.

Calculates the boiling point elevation of a solution using the ebullioscopic constant, molality, and van't Hoff factor.

Calculates the boiling point of a substance at a given pressure using the Clausius-Clapeyron equation.
