Study Notes
Reaction of Carbonates with Acids
- Excess carbon dioxide reacts with calcium carbonate, water to produce calcium hydrogencarbonate.
- Limestone, chalk, and marble are forms of calcium carbonate.
- Metal carbonates and hydrogencarbonates react with acids to produce salt, carbon dioxide, and water.
- The general equation for this reaction is: Metal carbonate/Metal hydrogencarbonate + Acid → Salt + Carbon dioxide + Water
Reaction of Acids and Bases
- Adding dilute sodium hydroxide (NaOH) solution to phenolphthalein creates a colorless solution.
- Adding dilute hydrochloric acid (HCl) dropwise to the solution causes a color change in phenolphthalein.
- Phenolphthalein turns colorless in acidic solutions.
- Adding drops of sodium hydroxide causes the pink color to reappear, showing the reaction is reversible.
- The effect of a base is nullified by an acid, and vice versa in a neutralization reaction. The general equation is: Base + Acid → Salt + Water
Reaction of Metal Oxides with Acids
- Adding a small amount of copper oxide to dilute hydrochloric acid in a beaker causes a color change.
- The solution changes from blue to blue-green and the copper oxide dissolves.
- The blue-green color is due to the formation of copper(II) chloride.
- The general reaction between a metal oxide and an acid is Metal oxide + Acid → Salt + Water.
- There is a reaction between copper(II) oxide and an acid that causes copper oxide to dissolve into the solution with a blue-green color.
