- Salt is made up of Sodium and Chlorine.
- Salt has negatively charged ions (OH-) and positively charged ions (H+).
- Due to their oppositely charged ions, the ions are attracted towards each other with an electrostatic force of attraction which is called an ionic bond.
- An equal number of opposite charges makes the ionic compounds neutral with no charge.
- Salt water is a good conductor of electricity.
- Salts are ionic in nature due to the presence of ions.
- They are brittle, hard and crystalline solids.
- Salt is white, odorless and it has a salty taste.
- All potassium (K), ammonium (NH4+) and sodium (Na) salts are soluble in water (H2O).
- Nitrites, nitrates, and bicarbonates can be dissolved in water.
- All metallic oxides, metallic carbonates, hydroxides, phosphates, and sulphides are insoluble in water.
