In a bid to combat food waste and enhance safety, researchers have introduced a pioneering method for gauging the freshness of raw beef using on-pack pH indicators. This new system provides consumers ...

Experiment #1 – Is it an acid, base or neither? The pH scale (which ranges from 0 to 14) gives us the ability to understand how acidic (pH lower than 7) or basic (pH higher than 7) an item is. We can ...

Watch a simple but fascinating chemistry experiment using phenolphthalein and dry ice to demonstrate pH changes in real time. See how carbon dioxide forms acid in water and causes a dramatic color ...
