Calculators

Calculates the normality of an acid or base solution using titration data. This calculator is based on the principle of neutralization in acid-base reactions.

Calculates the mass percentage of a component in a mixture.

Calculates the molecular weight (also known as molar mass) of a chemical compound based on the sum of the atomic weights of each element in the molecular formula.

Calculates the pH, pKa, or the ratio of acid and conjugate base concentrations using the Henderson-Hasselbalch equation. This equation is commonly used in chemistry, biology, and medicine to estimate the pH of a buffer solution.

Calculates the dilution factor, final volume, initial volume, or final concentration based on the given inputs. Dilution is the process of reducing the concentration of a solute in a solution, usually simply by mixing with more solvent.

This calculator helps you convert between different concentration units, including molarity (mol/L) and percentage concentration (% w/v, % v/v, % w/w).

Calculates the pH of a buffer solution using the Henderson-Hasselbalch equation.

Calculates the amount of bleach and water needed to achieve a desired chlorine concentration for disinfection purposes.

Calculates the alligation ratios needed to mix two solutions of different concentrations to achieve a desired intermediate concentration.

Calculates the activity coefficient of an ion in a solution using the Debye-Hückel equation or its extended versions.
