Fizz, Hydrogen gas released leaving an alkaline solution of metal hydroxide 1 of 32 What happens when you react potassium, sodium and lithium with dilute acid? Explode 2 of 32 What happens when you react magnesium, aluminium, zinc and iron with water? Its a very slow reaction 3 of 32 What happens when you react calcium, magnesium, aluminium, zinc and iron with dilute acid? Fizz giving off hydrogen gas and forms a salt 4 of 32 What happens when you react tin and lead with water? Slight reaction with steam 5 of 32 What happens when you react tin and lead with dilute acid? React slowly with warm acid 6 of 32 What happens when you react copper, silver and gold with water? Nothing 7 of 32 What happens when you react copper, silver and gold with dilute acids Nothing 8 of 32 What is the rule with metals and aqueous solutions? A more reactive metal will displace a less reactive metal from an aqueous solution of one of its salts 9 of 32 What does an ionic equation only do? Only shows the atoms and ions that change in a reaction 10 of 32 What is oxidation? Adding oxygen and losing electrons 11 of 32 What is reduction? Removal of oxygen and gain of electrons 12 of 32 What do some ores need to have done before they are extracted and purified? Concentrated 13 of 32 What is the reactivity series? Potassium, sodium, calcium, magnesium, aluminium, carbon, zinc, iron, tin, lead, hydrogen, copper, silver, gold and platinum 14 of 32 What is a mnemonic for the reactivity series? Please stop calling me a cute zebra its too like hating cool smart guys playing 15 of 32 The oxides of metals below carbon can be reduced by what? Carbon to give metal element 16 of 32 Metals more reactive than carbon are extracted how? By electrolysis of the molten metal compound 17 of 32 What is a salt? The compound formed when the hydrogen in an acid is wholly or partially removed by metal ions 18 of 32 What is the formula for a metal and an acid? Metal+acid= a salt+hydrogen 19 of 32 What salt is formed with hydrochloric acid? Chloride 20 of 32 Which salt is formed with sulfuric acid? Sulfate 21 of 32 What salt is formed with nitric acid? Nitrate 22 of 32 What are bases? Bases are compounds that can neutralise acids 23 of 32 General formula for a base and acid Acid+base= salt + water 24 of 32 What reaction is this called? Neutralisation 25 of 32 How can you get a pure sample of salt made in an acid-base reaction? Crystallised out of solution by evaporating and drying with filter paper 26 of 32 What is the formula for the reaction between an acid and an alkali? Acid+alkali= salt +water 27 of 32 How would you collect a pure sample of the salt? Carry out titration with indicator to see how much acid reacts completely with the alkali. Repeat without indicator and crystallise 28 of 32 What is the formula for an acid and a carbonate? Acid + carbonate = salt, water and carbon dioxide 29 of 32 How can you test for PH? Use Ph scale, Ph meter, electronic ph sensor 30 of 32 What do strong acids do? Ionise completely 31 of 32 As the PH decreases by one unit, the hydrogen ion concentration increases by a factor of? 10 32 of 32
