Chemistry Year 10 Mocks Neutralisation Flashcards
What is the pH for acids
Lower than 7
What is the pH for alkalis
Greater than 7
What’s the definition of neutralisation
When an acid reacts with an alkali to form salt and water.
When we use the following acids name the salt that is formed
Hydrochloric Acid
Sulfuric Acid
Nitric Acid
Chloride
Sulfate
Nitrate
Are the following hydroxides and oxides a base of an alkali
Sodium hydroxide
Calcium oxide
Magnesium hydroxide
Lithium oxide
Copper oxide
Sodium hydroxide - a base and an alkali
Calcium oxide - a base
Magnesium hydroxide - a base and an alkali
Lithium oxide - a base
Copper oxide - a base
What is the first form of neutralisation in everyday life
Brushing your teeth - using toothpaste helps to neutralises the acid and prevents tooth decay as it’s an alkaline
What is the second form of neutralisation in everyday life
Treating bee stings - bee stings are acidic and can be treated using an alkaline, e.g. Baking powder
What is the third form of neutralisation in everyday life
Treating wasp stings - they are alkaline, so vinegar can cure them as it is acidic
What is the fourth form of neutralisation in everyday life
Acidic soil - plants don’t grow well in acidic soil, we treat this soil with like fertilisers e.g. Limestone to neutralise it
