Testing ph

Aim: To test the PH of a range of household chemicals.

Equipment: a variety household chemical, spotting tile, red litmus paper, blue litmus paper, universal indicator solution, safety glasses.

Method: add a few drops.of each chemical to a spot on your spotting tile. If a substance is solid or powdered you will need to mix it with a few drops of water before testing it.

Test chemicals with litmus papers.

Test each chemical with a few drops of universal indicator.

Results:

Chemical being tested	Colour in blue litmus	Colour in red litmus	Colour in the universal indicator
Pledge Clean & Dust			Red-orange
Morning fresh			green -yellow
water			green-blue
Jif			white-violet
Active fresh			Light blue-orange
Sulfuric Acid			Clear acid-red
Sodium Hydroxide			Clear acid-blue

Conclusion:

Chemical being tested	Acid or base	Evidence from the investigation.
Pledge clean & dust	Acid	Universal indicator
Morning fresh	Acid	Universal indicator
Water	Base	Universal indicator
Jif	base	Universal indicator
Active fresh	acid	Universal indicator
Sulfuric acid	acid	Universal indicator
Sodium Hydroxide	base	Universal indicator
