An acid-base titration is a neutralization reaction that is performed in the lab in order to determine an unknown concentration of acid or base. Based on the molar ratio between HCl and NaOH you know that at the equivalence point: Molarity (M) is moles per liter of solution, so you can rewrite the equation to account for molarity and volume: Rearrange the equation to isolate the unknown value. The moles of acid will equal the moles of base at the equivalence point. 55 M NaOH, you can calculate the concentration of hydrochloric acid, [HCl]. **Acid base titration lab report pdf.** N this care, you are looking for the concentration of hydrochloric acid (its molarity): If you know that titrating 55. So, if you know one value, you automatically know the other.

55 ml of 6.

Here s how to perform the calculation to find your unknown.

55 ml of an HCl solution requires 75.

For example, if you are titrating hydrochloric acid with sodium hydroxide: You can see from the equation there is a 6: 6 molar ratio between HCl and NaOH.
