Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Procedure: Place 25 mL sample of vinegar, which contains acetic acid, CH3COOH, in a 250 mL Erlenmeyer flask. Then add 3-5 drops of phenolphthalein solution in the vinegar inside the flask. In the base burette, place 0.4600 M NaOH up to the zero mark. Slowly add the NaOH solution from the burette to the vinegar in the flask, with constant but careful swirling of the content of the flask upon each addition of NaOH. Continue the dropwise addition of NaOH from the burette until the color of the solution in the flask changes to a very pale pink, which indicates the end of titration. Make sure that the burette does not touch the flask or its content. Do the same procedure for two more samples of vinegar.
