1. Salts are ionic compounds formed from the reaction of an acid and a base, typically through a reaction.
2. The process where a salt reacts with water to produce acidic or basic solutions is known as .
3. According to the solubility rules, all nitrates are in water.
1. Describe two methods for the preparation of soluble salts, providing a balanced chemical equation for each.
2. Explain why a solution of sodium carbonate (Na₂CO₃) is alkaline while a solution of ammonium chloride (NH₄Cl) is acidic.
1. All salts are soluble in water.
True
False
2. The pH of a salt solution formed from a strong acid and a strong base is always 7.
True
False
Observe the image of mineral crystals below. Many salts, like sodium chloride, form similar crystalline structures.
1. Briefly describe the arrangement of ions in an ionic crystal lattice.
2. How does the strong electrostatic force within the crystal lattice influence the physical properties of salts?
