salt reactions

• Reactions between acids and different kinds of bases result in neutralization reactions
• Metal oxides and hydroxides, when reacting with acids, form a salt and water
• Example: Hydrochloric acid + sodium oxide → sodium chloride + water
• Example: Sulfuric acid + potassium hydroxide → potassium sulfate + water
• When acids react with metal carbonates, they form a salt, water, and carbon dioxide
• Example: Nitric acid + calcium carbonate → calcium nitrate + water + carbon dioxide
• Soluble salts are formed when acids react with insoluble bases like metal oxides, hydroxides, or carbonates
• Steps to make soluble salts using an insoluble base and acid:
• Place dilute acid in a beaker and gently heat it with a Bunsen burner
• Add insoluble base slowly until it stops disappearing, indicating excess base
• Filter out excess base using filter paper and funnel
• Heat the filtered solution to evaporate water and form solid crystals of the salt
• Filter out the crystals, dry them, and collect the pure solid crystals of the soluble salt
