Question

pH Lab Activity :

The pH scale measures the amount of H+ ions within a solution. Acids are solutions that have a high amount of H+ ions, while solutions with a low amount of H+ ions are called bases. Bases however have a high amount of hydroxide (OH-) ions, while acids have a low amount of hydroxide ions. Universal litmus paper can indicate whether a solution is an acid or a base, and indicate the strength of the acid or base. The initial color of a universal pH paper is orange, but it will change colors depending on the strength of the acid or base. In this activity, you will measure the pH of various household items.

So far I have tried with HCl, lemon juice, vinegar, grapefruit, tomato juice, black coffee,pure water, toothpaste, baking soda, ammonia solution, bleach and Liquid drain cleaner.

Please provide me some more household items and their pH values. Thanks in advance.

Explanation / Answer

Try cocacola (pH~3), milk (pH~6), battery acid (ph~0), drain cleaner (pH~14,), shampoo (pH~5), tap water (ph~8)

You can try saliva and urine (its gross !!) also which have a pH~6
