C8 Acids, Bases and Salts (Combined Science)

Here are some key terms for this topic: Key Terms C8

GCSE Bitesize has revision pages (that take you through the topic), a test and an activity – scroll down to Acids, Bases and Salts. GCSE s-cool – Acids & Alkalis – revision notes & animations, practise exam questions & a revision summary. Skoool Chemistry – click on ‘7.Acids, Alkalis & Salts’ for excellent lessons that take you through the topic; also a glossary of terms. Chemactive worksheets & answers just click on Acids & Alkali questions. Also worksheets from Mr Guch that cover Acids, Bases & SolutionsFor Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down.

C8.1 THE CHARACTERISTIC PROPERTIES OF ACIDS & BASES

A bit of revision:

Reactions of acids from baha696969

GCSE Bitesize – Acids, Bases & Salts (5m 23s):

Bitesize Top 20 Science Demos – Acids & Alkalis (3m 12s). Also (in American) is a 14m 13s video on Acids & Bases.

Coke Cans in Acid and Base from the Periodic Table of Videos. All about that Base (no acid) – musical parody.

C8.2 PREPARATION OF SALTS

The powerpoint ‘Acids, Bases & Salts‘ (above) covers this subtopic very well.

C8.3 IDENTIFICATION OF IONS & GASES

The Virtual School video clips on how to test for gases, for anions (carbonates, sulphates & nitrates), for cations (copper, iron, zinc & ammonium) and ammonium ions (2nd half) .

IGCSE Chemistry, a 25m lesson from ChemistryKlipz covers testing for ions from 19m 45s to 25m 30s.

For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ’23.Chemical Tests for Identification’.

This powerpoint revises group properties (from C9 The Periodic Table) and then covers testing for ions & gases:

6.1 Digestion & Absorption

BioKnowledgy Presentation on 6.1 Digestion and absorption from Chris Paine

A fantastic animated tutorial from McGraw Hill Education on the Organs of Digestion & one on the action of Sucrase.

How to draw and label a diagram of the digestive system – a video from Stephanie Castle (you need to be able to annotate this diagram).

Mr Paul Andersen (from Bozeman High) details The Digestive System in a 9m 38s tutorial:

In Crash Course Biology #28 – The Digestive System, Hank takes us through the bowels of the human digestive system and explains why it’s all about surface area.
