Frequently asked questions
What is Topic C4: Predicting and identifying reactions and products?
Topic C4: Predicting and identifying reactions and products covers Predicting chemical reactions and Identifying the products of chemical reactions in GCSE OCR Higher Chemistry. 27 lessons in 2 subtopics.
What is the order of the metal reactivity series?
The metal reactivity series, from most reactive to least reactive, is potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, copper. The Metal Reactions and the Reactivity Series notes cover this in full.
What is the test for hydrogen?
The test for hydrogen is to hold a burning splint at the mouth of the test tube: if hydrogen is present, it burns rapidly with a pop sound. The Testing for hydrogen gas notes cover this in full.
How do you test for sulfate ions?
To test for sulfate ions, add a few drops of dilute hydrochloric acid to the solution, then add barium chloride solution. The Testing for Sulfate Ions notes cover this in full.
What are the noble gases?
The noble gases are the Group 0 elements helium, neon, argon, krypton, xenon and radon. The Trends in Noble Gas Properties notes cover this in full.
What is the test for oxygen?
The test for oxygen is to put a glowing splint into a test tube of the gas: if oxygen is present, the splint relights. The Testing for Oxygen Gas notes cover this in full.
What is the test for carbon dioxide?
The test for carbon dioxide is to bubble the gas through limewater, or shake it with limewater: carbon dioxide turns limewater milky (cloudy). The Testing for Carbon Dioxide Gas notes cover this in full.
What is a displacement reaction?
A displacement reaction is a reaction where a more reactive element takes the place of a less reactive element in a compound. The Displacement Reactions and the Extended Reactivity Series notes cover this in full.
What is a redox reaction?
A redox reaction is one in which oxidation and reduction both occur. The Understanding Oxidation and Reduction with Electrons notes cover this in full.
