NaOH + HCl → NaCl + H 2 O NaOH solution should be titrated against methyl orange or phenolphthalein. Acid Base Titration Lab Report Words | 7 Pages. The acid and base titration uses the Arrhenius theory. This theory states “that acid are substances which produce hydrogen ions in solution and bases are substance which produce hydroxide ion in solution.”.
Although acid-base titrations are carried out in the liquid phase, one or more steps Titrating a Hydrochloric Acid Solution with a Standard Sodium Hydroxide Solution book involves weighing a solid reagent on a balance. Sodium hydroxide, for example, is standardized by titrating potassium hydrogen phthalate (KHP) that is.
A sodium hydroxide solution was standardized by titrating 25mL of M standard HCl. The initial buret reading of the sodium hydroxide was mL and the final reading was mL.
What was the molarity of the base solution. For inexperienced students its titrations against strong base are easier to perform. This article presents a neutralization titration of a citric acid solution by sodium hydroxide solution in a format suitable for beginner titrators.
