how to separate vinegar and water ?? no internet answer
Answers
Vinegar is about 5% acetic acid. You must really be desperate, but since you asked. Titrate the solution with sodium hydroxide until you have a ph of 9 or 10, then distill off the water. The residue is a mixture of sodium acetate and sodium hydroxide. You now have recovered the water.
Take the residue and add some sulphuric acid to a pH of about 6. Distill off the acetic acid and the residue will be sodium sulfate and sulfuric acid. You have now recovered the acetic acid....
Five acetic acid recovery processes are generally consid- ered: (1) azeotropic distillation, (2) simple distillation, (3) solvent extraction followed by distillation, (4) chemical treatment, and (5) adsorption.
Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
Vinegar, on the other hand—or a mixture of 4 to 6 percent acetic acid and water—is not easily separable by distillation. This is because the boiling points of water (100 degrees C) and vinegar (about 100.6 degrees C) and are too close together to result in a full separation of both components.
