IGCSE Chem Topic 13 – Carbonates

IGCSE Chemistry: topic 13 Carbonates, a 7m 25s video lesson by Sal Sciab:

What is the Limestone Cycle? in 4m (The Virtual School):

What are the uses of Limestone? in 5m (The Virtual School):

Scientific EyeLimestone (a 19m video).

GCSE Bitesize has revision pages (that take you through the topic), a test and an activity – just scroll down to ‘Limestone and building materials’. For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ’10.Limestone Uses and Chemistry’. 

Finally, three short videos – Limestone Intro (1m 57s), Changing limestone – the reactions of limestone (1m 55s) & limestone – Neutralizing acid soil (3m 9s).
