Question

and conclusions Part / pH measurements Substance pH (from paper) pH (from meter) acid or base? Vinegar Ammonia Fruit Juice Lye Carbonated water Fertilizer Baking soda Shampoo Color of phenolphthalein in HCI Color of phenolphthalein in NaOH Therefore : What color is phenolphthalein in any acidic solution? What color is phenolphthalein in any basic solution? What color is red litmus paper in acid? What color is red litmus paper in base? What color is blue litmus paper in acid? What color is blue litmus paper in base? Part 2 Buffers pH of Buffer 1 pH of water pH of buffer 1 and HCI pH of water and HCI

Answer 1

The pH measurements depend only the sample used. But the neature of the substances are mostly same i.e if it is acidic or basic. As for example pH of a shampoo can vary from 5 to 7. If a good shampoo is taken for pH measurement it will be neither too acidic not too basic. Now the short questions of colors of indicators are given below and these are perfect question as it's mentioned the solution acidic or basic. The answers are given below:

11.0 Base. 3.35 13.3 Substance | Bref mom fußer) | BH(from meter) a bone vinegar 2.4 to 4.4 3.25 I Acid Ammonia 11.6 (approx). Acid Fruit Juice mostly 2.3 to 4.2 Ir different that have Kadifferent (H) Base Lye 14 Carbonated . 3 to 4 water 7.05 Neutral (maybe.

Color color of of phenolphthalein in Ace = Phenolphthalein in Nach - colorless Pink Therefore: what color is phenolphthalein in any acidic solution ? Colorless what color is phenolphthalein in any basic solution ? Pink what acid? color Red is ned litmus on no change paper in of color what color is red litmus paper in base? blue litmus paper in acid? is blue what color Red " what color in blue litmus e or no change paper in boxe ? of color.
Part 2 Buffers

pH of buffer 1 : _______ ( need to know the composition of buffer which is not supplied)

pH of water : 7

pH of buffer 1 and HCl : __________ ( if small amount of HCl added the pH will be the same as the pH of buffer 1)

pH of water and HCl : _________( it will be less than 7, depend on the concentration of HCl and amount of water.)
