Question

How do acids feel?

Answer 1

Hint: Some acids like weak acids are present in fruits and vegetables and can be consumed while some strong acids are harmful and cannot be consumed. The acids are those species which can donate its hydrogen ion which is released on dissolving in water.

Complete answer:
Acids are the chemical species which on dissolving in water release hydrogen ions or protons which are abstracted by the base compound. When a blue litmus paper is dipped in the acidic solution it changes the blue litmus to red litmus. The pH of the acids are considerably lower and the value is below 7.
The acids can be classified into strong acids and weak acids. The strong acids on dissolving in water fully dissociate into its constituent ions. Example: hydrochloric acid, sulphuric acid. The weak acids on dissolving in water partially dissociate to give its constituent ions. Example: formic acid, acetic acid.
Strong acids are very corrosive in nature. The strong acid cannot be touched or used by naked hands, always wear gloves while handling or working with strong acids. If accidently the strong acid comes in contact with the metal it corrodes the metal and if touched burns the skin.
Some generally weak acids are present in everyday life and are consumed. The acids are generally sour in taste. They are available in fruits and vegetables. The acid present in lemon is citric acid, tomato contains citric acid and malic acid. The vinegar is manufactured industrially from weak acid acetic acid mixed in water. The weak acids are not that much harmful as compared to strong acids.

Note:
Strong acids are generally prepared in laboratories by chemical reaction. Some weak acids are present naturally. The strong acids can be diluted to different molar solutions and can be used for a long time.
