This video from our GCSE revision series, focusses on polymers. The video explains that alkenes are used to make polymers in a process called addition polymerisation. It also recaps the structure, properties and uses of addition polymers such as poly(ethene), poly(propene), poly(vinylchloride) and poly(tetrafluoroethene)

This video from our GCSE revision series, focusses on titration calculations. The video explains that titrations can be used not only to add the exact volumes of acid or alkali needed for neutralisation but also to calculate the concentrations of solutions. It also recaps the steps required to solve simple titration calculations and how to use these to find the concentrations of acids and alkalis.

This video from our GCSE revision series, focusses on the manufacture of sulfuric acid during the Contact Process. The video recaps what happens in the main stages of the Contact Process and how to write chemical and word equations to describe each stage. It also discusses concentrated sulfuric acid's role as a dehydrating agent and its effect on sugar and hydrated copper (ii) sulfate.

This video from our GCSE revision series, focusses on alcohols. It recaps how to name and draw structural formulae for alcohols and explains how ethanol can be made from sugars during fermentation. The uses of ethanol along with their social, economic and environmental impacts are also discussed.

This video from our GCSE revision series, focusses on energy changes. The video revises the differences between endothermic and exothermic reactions and how to use bond energy data to calculate the overall energy change for a reaction and to identify whether it's exothermic or endothermic

This video from our GCSE revision series, focusses on Smart Materials. The video revises the properties and uses of smart materials including thermochromic pigments, photochromic pigments and polymer gels.

This video from our GCSE revision series, focusses on the production of ammonia during the Haber process. The video explains the reaction conditions and how to write a word and balanced chemical equation for the reaction taking place.

This video from our GCSE revision series, focusses on the extraction of iron and aluminium. Through a series of practice questions, the video revises how iron can be extracted from iron ore in a blast furnace. It also discusses how aluminium can be extracted from its ore using electrolysis and how this process works.

This video from our GCSE revision series, focusses on making and naming salts. After watching this video, students should have an improved understanding of how salts can be made from reacting acids with insoluble bases, alkalis, metals and metal carbonates. They should also be able to explain how crystals of salts can be obtained from the reactions of insoluble bases and metal carbonates with a...

This is the second video in a new GCSE revision series. After watching this video, students should have an improved understanding of how to name and represent different hydrocarbons using molecular and structural formula. They should also understand that alkenes undergo addition reactions with hydrogen and bromine and that the reaction with bromine is used as a chemical test for an alkene

This is the first video in a new GCSE revision series. After watching the video, students should have an improved understanding of how to illustrate the bonding in various compounds using dot and cross diagrams. They should also be able to explain how the properties of substances are linked to their structure and bonding.

This video aimed at GCSE students, recaps the steps required to solve simple titration calculations and how to use these to find the concentrations of acids and alkalis. It also shows students how to use experimental data from titrations to find other values such as volumes of acid and alkali needed for neutralisation.

This video aimed at GCSE students, explains that titrations can be used not only to add the exact volumes of acid or alkali needed for neutralisation but also to calculate the concentrations of solutions. It also explains the steps required to solve simple titration calculations and how to use these to find the concentrations of acids and alkalis.

This video aimed at GCSE students, recaps the term concentration and how to calculate concentrations of solutions in mol/dm3 from given masses of solute and volumes of solution. It then explains how to calculate the masses of solute required within a given volume of solution to produce certain concentrations of solutions in mol/dm3.
