The pre-lab video shows the amounts you need of each chemical. When recording your observations, record the initial color you observe upon addition of the cabbage juice. Then, using the information in the lab's introduction, approximate the pH of the substances and classify them as either ...
An acid aqueous solution has [H + ] > [OH − ], an alkaline solution has [H + ] < [OH − ], and a solution in which [H + ] = [OH − ] is said to be neutral. The most general idea of acids and bases is due to G. N. Lewis. A Lewis acid is a...

The pH scale measures acidity and ranges from 0 (highly acidic) to 14 (highly alkaline). Car battery acid has a pH of around 0 to 1, while milk of magnesia has a pH around 10. Perfectly pure water has a neutral pH of 7. Acids and bases neutralize each other because excess hydrogen...
