Chemistry

This audition was performed to identify two coat ions in an unbeknownst(predicate) base through observation collected from observing nightspot metal ions with many reagents. In this experiment the reactions of metal with sulphate ion were runneled by washing 9 4mL examen tubes and ascending them with distilled water. indeed 1 mL of individually(prenominal) of the 9 ions was fit(p) in a tryout tube. Then 1 mL of 1.0M N2SO4 was instituteed to each of the judge tubes and indeed got a cud located on it and then was centrifuged. The reactions of each of the guild ions were then record on to the table. The test was repeated with 9 more test tubes, the same metal ions but or else of the N2SO4, 1mL of KI was fetched to the test tubes, and then were stopple and centrifuged. attached then some other 9 test tubes were taken and or else of the N2SO4 or the KI, 1mL of Na2CO3 was added to the test tubes, hooplaed and centrifuged. The reaction was then to a fault e nter in the table. Next the reaction of metal ions with hydroxide ion was tested. In 9 unaccented test tubes one of the nine ions where added. Then 1 fall away of 6M NaOH was added to the test tubes with 3 extra drops added to the iron(III) process solution.

The observations then were enter into the table. Then add 1 mL of 6N NaOH to each test tube and was stoppered and centrifuged. Then clean out another 9 test tubes and add one drop of 6M HN3 to each of the nine test tubes adding three extra drops to the acidic iron(III) nitrate solution. Then stopper and centrifuge and record the reactions of the solutions in the information table. Then add 1 ml of 6M NH3 to the test tubes stopper and shake each of the test tubes. The reacti! on then was recorded into the table. Then observations that where notice and recorded into the data table where give to conduct an experiment to determine what the unknown solution is.If you take to get a full essay, order it on our website: OrderEssay.net
