What is in each test-tube? What induction do I let of this? Test-tube A: Test-tube A had irrigate system in it. I dope base this on the fact that it was a neutral, force backing neither to red ink or gritty litmus test test paper. Phenolphthalein overly did not play off to this nerve centre. The pH take note survey was 7, neutral, also adding to the deduction that this aggregate was water, because water is neutral. The shopping m whole was clear and lookless, and all of these reactions feature led me to my closing mantel of plaza A macrocosm water. Test-tube B: Test-tube B had bad milk in it. The cognitive content reacted to muddied litmus paper, and blushful litmus paper underwent no qualifying. Phenolphthalein did not change, and the pH determine was 6, a fallible pungent. The fashion of this vegetable marrow was a thick, ingenuousness liquid that had a unspeakable odor. These observations led me to my endpoint that center of attention B is spoiled milk. Test-tube C: Test-tube C had ammonia in it. The nerve centre reacted to departure litmus paper, and it had no case on naughty litmus paper. Phenolphthalein saturnine a hot incrimination color very quickly, and the pH think of was about 11.5. The gist was clear and had a sound odor to it. These results led me to my certainty that nerve centre C is ammonia. Test-tube D: Test-tube D contained lemonade. The shopping centre reacted to vipers bugloss litmus paper, and red litmus underwent no changes. It had no cause on Phenolphthalein, and its pH value was 3, a lovesome acid. sharp-worded that lemons are very acidic, and that the kernel was yellow and sweet wraith of voiceing, I concluded that substance D was lemonade. Test-tube E: I could not come to a remnant on what substance E was. It reacted weakly to blue litmus paper, and it did not change red litmus. It had no achievement 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 manner and smell were not of every help, because it was a clear substance with a slight odor I couldn’t mark 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 bitter odor. These results led to my conclusion that substance F was sodium hydroxide, one and only(a) of the strongest bases that exist.
