What’s the formula for titration?

C1V1 = C2V2 Where: C1 is the concentration of the first solution (in mol/L or Molarity) V1 is the volume of the first solution used (in liters) C2 is the concentration of the second solution (in mol/L or Molarity) V2 is the volume of the second solution used (in liters) This equation is based on the principle of conservation of moles. It states that the number of moles of a substance in a solution is constant, before and after the reaction. During a titration, a known volume and concentration of one solution (the titrant) is added to another solution of unknown concentration (the analyte) until the reaction between the two is complete. By measuring the volumes of the solutions used, you can determine the unknown concentration. To use the formula, you need to identify which solution is the titrant (with the known concentration) and which is the analyte (with the unknown concentration). Then, measure the volumes of each solution used during the titration. Plug the values into the formula and solve for the unknown concentration (C2). I hope this helped.
