A metal salt and hydrogen are formed 1 of 13 What happens when a metal oxide is reacted with a dilute acid? A salt and water are formed 2 of 13 What happens when a metal hydroxide is reacted with a dilute acid? A salt and water are formed 3 of 13 What happens when a aqueous ammonia is reacted with a dilute acid? Forms an ammonium salt 4 of 13 What happens when a carbonate or a hydrogencarbonate is reacted with a dilute acid? Salt + Water + Carbon Dioxide formed 5 of 13 What is a base? An oxide, hydroxide or a carbonate of a metal (or ammonia) 6 of 13 What happens when a base reacts with an acid? A salt and water are formed 7 of 13 What happens when an alkali reacts with an ammonium salt? Salt + Ammonia + Water formed 8 of 13 How is the soil neutralised? Lime or limestone is added to it. 9 of 13 What are basic oxides? Basic oxides are usually metallic. Those of group 1 and 2 react with water to form an hydroxide. 10 of 13 What are acidic oxide? Most non-metal oxides are non-acidic. They react with alkalis to give a salt and water, and also react with bases. 11 of 13 Which oxides are neutral? Nitrogen(ii) Oxide and Nitrogen(i) oxide 12 of 13 Which oxides are amphoteric? Those that have both acidic and basic properties. Examples are zinc and aluminium oxides 13 of 13
