SUMMARY
To detect an acid, the scientists use indicators. Litmus is one indicator. An acid turns blue, litmus red. Acids are a group of chemicals with very similar properties. An acid is a sour-tasting substance. Lemons taste sour because they contain citric acid. The sour milk contains lactic acid while the sour taste of vinegar is due to acetic acid. Acetic acid, which is an ingredient of vinegar, releases only a limited number of ions and is not a strong acid. All these are weak acids. This is the reason why it can be used safely in our food.
