Study Notes
Acid-Base Reactions
- A neutralisation reaction between an acid and a base produces a salt and water.
- The general reaction between a metal oxide and an acid is the formation of a salt and water.
- Copper oxide reacts with dilute hydrochloric acid to produce copper chloride and water.
Neutralization Reaction
- The product of an acid-base neutralization reaction is a salt and water.
- The reaction between an acid and a base results in the nullification of the acid and base properties.
Chemical Formulas
- The chemical formula for limestone is CaCO3.
- The chemical formula for hydrochloric acid is HCl.
Acid-Carbonate Reactions
- The main product when a metal carbonate reacts with an acid is a salt, water, and carbon dioxide.
pH Indicators
- The color of phenolphthalein solution changes from colorless to pink when NaOH is added to it.
Acid-Base Neutralization
- The effect of a base is nullified when it reacts with an acid to form a salt and water.
Reaction Products
- The main products of the reaction between NaOH(aq) and HCl(aq) are NaCl(aq) and H2O(l).
This quiz covers the reactions of metal carbonates and hydrogencarbonates with acids, leading to the formation of salts, carbon dioxide, and water. It also discusses the different forms of calcium carbonate and the general summary of the reaction.
