Ethonoic and citric 2 of 26 What alkali is caustic? Sodium hydroxide 3 of 26 What is an indigestion remedy? Magnesium hydroxide 4 of 26 PH scale strengths? Strong acid (0-2) weak acid (3-5) neutral (7) weak alkali (9-11) strong alkali (12-14) 5 of 26 What does acid release? H+ ions 6 of 26 What does a base absorb? H+ ions 7 of 26 What does an alkali have? A soluble base 8 of 26 Neutralisation equation? Acid + alkali - salt + water 9 of 26 What produces something different during neutralisation? Hydrogen ion + hydroxide ion = water 10 of 26 Why is there no change to the sodium ions and chloride ions? They are dissolved in water as a salt 11 of 26 Acid + Metal? Salt + hydrogen 12 of 26 What is the hydrogen test? Using a lighted splint against hydrogen causes a squeaky pop and creates bubbling 13 of 26 What reaction is an acid and metal? An exothermic reaction- it releases heat 14 of 26 Acid + metal oxide? Salt + water 15 of 26 What type of reaction is this? Exothermic reaction- releases heat 16 of 26 Acid + metal hydroxide? Salt + water 17 of 26 What type of reaction is this? Exothermic releases heat 18 of 26 Acid + metal carbonate? Salt + water + CO2 19 of 26 What type of reaction is this? Exothermic and effervesces 20 of 26 What is observed when acid reacts with carbonate? Fizzing, bubbles are seen because CO2 is a gas 21 of 26 How do you test for carbon dioxide? Using limewater 22 of 26 How do you know if it's present? Turns milky white and causes bubbling/fizzing during the experiment 23 of 26 Hydrochloric becomes? Chloride 24 of 26 Sulfuric becomes? Sulfate 25 of 26 Nitric becomes? Nitrate 26 of 26
