Purpose: The purpose of this experiment is to observe chemical changes in common consumer products to determine if the chemicals are basic, acidic, or remain neutral when mixed with other chemicals.
Procedure: In this experiment, various chemicals were mixed together, to determine a reaction. Using two drops from chemical 1 and two drops of chemical two, unless otherwise stated, then recording the type of physical reaction or color changes that occurred.
Well#/questions Chemicals Reactions
and HCI - C0
When combined Sodium Bicarbonate and Hydrochloric Acid, Carbon Dioxide is produced. The two chemicals do not undergo a change in color but a chemical change when CO2 is produced.
B HCI and BTB When Hydrochloric acid and Bromothymal blue are combined there is a physical change. The combination results in a yellowish tint. This means the byproduct of the two is a base.
and BTB When two drops of Ammonia and one drop of Bromothymal blue are combined the result remains blue. This means they are base.
D HCI and blue dye When Hydrochloric acid and blue dye are combined the result is a base.
E Blue dye and NaOCI When Blue dye and Sodium Hypochlorite react are combined the result is green. This means it is a base.
F NaOCI and KI When Sodium Hypochlorite and Potassium Iodide are mixed the two combined produced a reddish color. This means the combination made an acidic mixture. When starch is added the mixture turns black.
G KI and Pb(NO
When Potassium Iodide and Lead Nitrate are mixed they produce a yellowish color byproduct that is much thicker than the rest of the reactions.
H NaOH and phenolphthalein Sodium Hydroxide and Phenolphthalein produce a red mixture. This means the combination made an acidic mixture.
I HCI and phenolphthalein When Hydrochloric acid and phenolphthalein are mixed there was no change. Meaning the mixture is neutral.
J NaOH and AgNO
