Explain the term atomicity and Precipitation reaction. |
|
Answer» Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms.A precipitation reaction refers to the formation of an insoluble SALT when two SOLUTIONS containing soluble salts are combined. The insoluble salt that falls out of solution is KNOWN as the precipitate, hence the reaction's name. Precipitation reactions can help DETERMINE the PRESENCE of various ions in solution. |
