Lab # 11 – Acid - Base Titration
Introduction:
The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated.
Theory:
Solutions are made up of solvents and solutes. Materials known as acids when dissolved in water produce H+ ions. Acids are the proton donators. All of the inorganic acids are aqueous solutions. A base is a material that can neutralize acids. Bases when dissolved in water produce OH- ions. Bases are the proton acceptors. …show more content…
Titrating allows for the concentration or molarity of an unknown acid or base to be found. This can be done by titrating the acid solution against a base solution of which the molarity is known. The resulting reactants of an acid reacting with a base are water and a salt. This type of reaction is known as a neutralization reaction because the products of which are assumed to be neutral. Careful titration of an acid against a base until neutralization is reached allows for the assumption that moles of H+ = moles of OH-. The following relationship allows for the unknown molarity to be
