All acids contain one or more hydrogen atoms, but not all substances containing hydrogen are acids. Support this statement with examples. |
| Answer» Solution :HCl (hydrochloric acid), `H_2SO_4` (sulphuric acid) and `HNO_3` (Nitric acid) are all examples of inorganic acids. They all have the HYDROGEN atom in common. Most acids essentially contain ONE or more hydrogen atoms. Whereas water `(H_2O)` also contains hydrogen, but it is not an acid. Similarly molecule of methane and AMMONIA also contain hydrogen, but all these do not produce `H^+` ions in aqueous solutions. Therefore it can be SAID that all acids contain hydrogen, but all substances containing hydrogen are not acids." | |
