Acid-metal reaction

2008-01-20T17:04:00.000-08:00

Copper coins in concentrated nitric acid.

Boiling acid

2008-01-20T17:01:00.001-08:00

Acidic hot spring

Universal indicator & pH scale

2008-01-20T16:59:00.001-08:00

Use of the universal indicator in various alkaline/acidic solutions.

Acid-alkali titration

2008-01-20T16:54:00.000-08:00

Acid-base titration. Indicator used is Phenolphthalein which turns from pink (in alkali) to colourless (in acid).

Acid-metal reaction

2008-01-20T16:46:00.000-08:00

Hydrochloric acid + zinc give off hydrogen gas. Ignore the words in the video.

Acid-carbonate reaction: carbon dioxide test

2008-01-20T16:43:00.000-08:00

This experiment comprises the carbon dioxide test - using limewater (calcium hydroxide).

Acid-carbonate reaction

2008-01-20T16:41:00.000-08:00

Reaction between an acid (hydrochloric acid) and carbonate (calcium carbonate). The bubbling (effervescence) is due to the production of carbon dioxide.
