AQA new specification-Testing for gases-C10.3

C10-Chemical analysis-Gas test lesson created in accordance to the NEW AQA Specification (9-1). Designed for a low ability year 11 class, although content can be adjusted to suit any ability. Includes: slide animations, embedded videos and practice questions with answers on slides as well as method for each test. I strongly recommend that you allow your students to practice the Hydrogen pop test (if they're good), went down really well with my class and was easy for them to recall the method in the class test they did. The rest of the tests can be demonstrated fairly easily and personally getting each student to do every test would've taken me well over an hour.

The test for hydrogen uses a burning splint held at the open end of a test tube of the gas.
Hydrogen burns rapidly with a pop sound. The test for oxygen uses a glowing splint inserted into a test tube of the gas. The splint relights in oxygen.
The test for carbon dioxide uses an aqueous solution of calcium hydroxide (lime water). When carbon dioxide is shaken with or bubbled through limewater the limewater turns milky (cloudy).
The test for chlorine uses litmus paper. When damp litmus paper is put into chlorine gas the litmus paper is bleached and turns white.
