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’.
Great resources from the Australian International School – videos, powerpoints, worksheets, practicals, animations, flashcards etc.
This powerpoint revises group properties (from C9 The Periodic Table) and then covers testing for ions & gases:

Some information on solids, liquids and gases (including a decent animation) can be found here. And this is a video on States of Matter from The Virtual School:
Science Bank 4 (Motion of Particles): Part 1 – Brownian motion (to 4m 45s); Part 2 – diffusion (to 9m 45s); Part 3 – changes of state (to 14m 15s):
IGCSE Chemistry: Topic 1 part 1 Particulate Nature of Matter (6m 30s) & part 2 Diffusion (5m 35s), lessons by Sal Sciab.
Not on the syllabus, but interesting: the invisible motion of still objects:
