Depending on the strength of the acid or the base reacting, the salt shows acidic, basic or neutral properties. Ex ( The salts formed by the reaction between a strong acid and a strong base show neutral properties. Sodium hydroxide is a strong base. Hydrochloric acid is a strong acid. Sodium chloride formed by the reaction between them is a neutral salt.
• 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.
