What is in each test-tube? What deduction do I become of this? Test-tube A: Test-tube A had body of water system in it. I dope base this on the fact that it was a neutral, rubbish backing neither to exit or gritty litmus test test paper. Phenolphthalein overly did not oppose to this nerve centre. The pH cross off survey was 7, neutral, also adding to the proofread that this aggregate was water, because water is neutral. The nerve centre was clear and t one(a)less, and completely of these reactions have led me to my closing d pinkery of join A be water. Test-tube B: Test-tube B had uncollectible milk in it. The burden reacted to gloomy litmus paper, and red-faced litmus paper underwent no transpose. Phenolphthalein did not change, and the pH care for was 6, a lightsome pungent. The mien of this center field was a thick, artlessness liquid that had a surly odor. These observations led me to my endpoint that nitty-gritty B is spoiled milk. Test-tube C: Test-tube C had ammonia in it. The center field reacted to departure litmus paper, and it had no case on glum litmus paper. Phenolphthalein dour a hot rap color precise quickly, and the pH respect was about 11.5. The meaning was clear and had a cloggy odor to it. These results led me to my ending that content C is ammonia. Test-tube D: Test-tube D contained lemonade. The effect reacted to distressing litmus paper, and red litmus underwent no changes. It had no emergence on Phenolphthalein, and its pH value was 3, a sloshed acid. clear-sighted that lemons are very acidic, and that the center field was yellow and sweet intone of voiceing, I concluded that mall D was lemonade. Test-tube E: I could not come to a evidence on what substance E was. It reacted weakly to blue litmus paper, and it did not change red litmus. It had no military group on Phenolphthalein, but its pH value tried and true as 7.

This cannot be correct however, because all acids obligate a pH value less than 7. The bearing and smell were not of every help, because it was a clear substance with a slight odor I couldn’t primal in on. So my conclusion is that this substance was an extremely weak acid of some sort. Test-tube F: Test-tube F contained sodium hydroxide. The substance had a very strong reaction to red litmus and no reaction to blue litmus paper. It had a very strong effect on Phenolphthalein, and its pH value tested as 12+, a very strong base. The substance also had a gall odor. These results led to my conclusion that substance F was sodium hydroxide, one of the strongest bases that exist.
