Titration Calculator: Free Online Tool for Accurate Acid-Base Calculations

Our titration calculator simplifies determining the concentration of unknown acid or base solutions through precise acid-base titration methods. Titration is a quantitative analytical technique where a solution of known concentration (titrant) is added to an unknown solution (analyte) until the equivalence point is reached, often indicated by a color change or pH shift. This free tool uses the balanced equation nH⁺ · M_a · V_a = nOH⁻ · M_b · V_b to compute missing values like molarity, volume, or ions donated—simply input any five parameters and calculate instantly.

Designed for chemists, students, and researchers, it supports strong and weak acid-base systems, providing results for pH at various stages, equivalence points, and titration curves.

Step-by-Step Worked Example

Step-by-Step Worked Example

Problem: You titrate 25 mL of HCl with 0.1 M NaOH and it takes 30 mL of NaOH to reach the endpoint. Find the HCl concentration.

Step 1: Apply the formula

C1 × V1 = C2 × V2

Step 2: Insert known values

0.1 × 30 = C2 × 25

Step 3: Solve for unknown concentration

C2 = (0.1 × 30) / 25 = 3 / 25 = 0.12 M

Final Answer: HCl concentration = 0.12 M
