More Lessons for IGCSE Chemistry
A series of free IGCSE Chemistry Lessons (Cambridge IGCSE Chemistry).
What is an acid? Acid and alkali solutions, Metal oxides and non-metal oxides, Acid reactions in everyday life, Alkalis and bases, Characteristic reactions of acids, Acids and alkalis in chemical analysis, Salts, Preparing soluble salts, Preparing insoluble salts, Strong and weak acids and alkalis.
The following table shows the neutralisation equations when acid reacts with metal, base, metal oxide, metal carbonate, ammonia, and when base reacts with ammonium salt, non-metal oxide. Scroll down the page for examples and explanations.
A salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. The following table shows the patterns for the solubility of salts
. To help you remember, think of SPANE for soluble salts: Sodium, Potassium, Ammonium, Nitrates and Ethanoates. Scroll down the page for examples and solutions.
