Calculators

Calculates the activation energy of a chemical reaction using the Arrhenius equation. This calculator helps determine the minimum energy required for a reaction to occur.

Calculates the actual yield of a chemical reaction, given the theoretical yield and percent yield.

Calculates the molarity of an unknown solution using titration data.

Calculates the estimated Total Dissolved Solids (TDS) in water based on Electrical Conductivity (EC). TDS represents the total concentration of dissolved substances in water, typically expressed in parts per million (ppm) or milligrams per liter (mg/L).

Calculates the mass/volume percent, mass percent, and volume percent of a solution.

Calculates the hydrogen ion concentration ([H+]) of a solution given its pH value. This is a fundamental calculation in chemistry for understanding acidity and basicity.
