QuestionAnswer
What happens when there is excess Hydrochloric acid in the stomach? Indigestion
What is the name of the technique used to find out EXACTLY how much alkali there is in an indigestion tablet? Titration
What is the salt made when Sodium Hydroxide reacts with Sulphuric Acid? Sodium Sulphate
What is the salt made when Calcium Hydroxide reacts with Nitric Acid? Calcium Nitrate
What is the salt made when Potassium Hydroxide reacts with Hydrochloric Acid? Potassium Chloride
What is the salt made when Potassium Carbonate reacts with Sulphuric Acid? Potassium Sulphate
What is the acid needed to make Potassium Sulphate? Sulphuric Acid
What is the acid needed to make Potassium Nitric? Nitric Acid
What is the acid needed to make Potassium Chloride? Hydrochloric Acid
Name a toxic gas produced during electrolysis of brine Chlorine
Name 2 uses for Chlorine making Bleach and making PVC
What does PVC stand for? Poly Vinyl Chloride
Name the acid found in the stomach Hydrochloric acid
What is the TWO roles of Hydrochloric acid in the stomach? help digestion and kill bacteria
What kind of chemicals are chemicals that help remedy indigestion? Alkalis
What are the two gases made when water is electrolysed? Hydrogen and Oxygen
What is the test for Hydrogen gas? pops when in contact with a lighted splint
What is the name of the process where a compound is split by passing electricity through the compound? electrolysis
What is the chemical test for Chlorine gas? Turns litmus paper red before bleaching the litmus paper
What is the formula of Nitric Acid? HNO3
What is the formula of Sulfuric Acid? H2SO4
What is the formula for HydroChloric Acid? HCl
What is the word equation for the reaction between dilute sulfuric acid and Zinc Oxide? Sulfuric Acid + Zinc Oxide --> Zinc Sulfate + Water (do not get fooled by "dilute": it is simply water; it does not react)
What is the word equation for the reaction between dilute sulfuric acid and Zinc Carbonate? Sulfuric Acid + Zinc Carbonate --> Zinc Sulfate + Water + Carbon Dioxide (do not get fooled by "dilute": it is simply water; it does not react)
What is the word equation for the reaction between dilute sulfuric acid and Zinc? Sulfuric Acid + Zinc Oxide --> Zinc Sulfate + Hydrogen (do not get fooled by "dilute": it is simply water; it does not react)
What is the test for Oxygen gas? relights a GLOWING splint ["relights a splint" is not detailed enough]
What is the test for Carbon Dioxide? when BUBBLED through Limewater (1mark), the Limewater turns CLOUDY (1mark) ["puts out a flame" is not good enough: Nitrogen gas does that as well]
Define electrolysis When a COMPOUND is split/broken down into its ELEMENTS, when electricity is passed through the compound [Have you used the correct keywords]
What are the two products formed when you react an ACID with a metal OXIDE? a salt (the name of the salt is the first word of the acid and the metal) and WATER
What are the two products formed when you react an ACID with a metal HYDROXIDE? a salt (the name of the salt is the first word of the acid and the metal) and WATER
What are the two products formed when you react an ACID with a metal? a salt (the name of the salt is the first word of the acid and the metal) and HYDROGEN
What are the two products formed when you react an ACID with a metal CARBONATE? a salt (the name of the salt is the first word of the acid and the metal) and WATER and CARBON DIOXIDE
What type of chemical reacts with an Acid to produce Water? either a Metal Oxide or a Metal Hydroxide
What type of chemical reacts with an Acid to produce Hydrogen gas? a (reactive) metal
What type of chemical reacts with an Acid to produce Water and Carbon Dioxide gas? a metal Carbonate
name a plastic containing Chlorine PVC (aka PolyChloroEthene, aka PolyVinylChloride)
Give 2 reasons why we need HydroChloric acid in our stomach To digest food and to kill bacteria
Why do we pass gases from chemical industry through Calcium Carbonate To neutralise (1) the acidic gases (1)
What is the name of the reaction between an acid and a carbonate? Neutralisation
What type of chemical is an antiacid? An alkali
