How to make benzoic acid

This video shows How to make benzoic acid from sodium benzoate. Sodium benzoate is a food preservative called as E211. It is most widely used in acidic foods. From that I am going to show you how to convert this to benzoic acid. Warning ! Concentrate hydrochloric acid is highly corrosive. Be careful when handling chemicals. Basically what was done is first sodium benzoate was dissolved in distilled water and the solution was acidified and filtered the crude acid. After that the crude was re-crystallized to get pure acid. Educational Purposes Only ! If you like this video, give a big thumbs up and don’t forget to leave your comments and ideas.
