PART ONE: Before test began the cation’s initial qualities were observed. The "K" ^"+" and the "Z" "n" ^"2+" cations both had an initial clear color before other chemicals were added, while the 〖"Cu" 〗^"2+" had an initial blue color and 〖"Co" 〗^"2+" had an initial pink pigmentation. In first cation elimination test conducted, metal hydroxide test, when 6 M of NaOH was added three out of the four cations formed a precipitate. The "K" ^"+" did not form a precipitate from the ten drops. After ten drops of "Z" "n" ^"2+" cation formed a white precipitate that was clear on the bottom and top but was separated by cloudy white layer in the middle of the solution. As more solution was added more precipitate was formed. Forming a two layer precipitate,…show more content… "Z" "n" ^"2+" produced a bluish-green flam that was blue through the cobalt glass. Copper (II) produced a unified green flame that appeared blue-green through the cobalt glass. The Cobalt (II) seemed to produce an orange flame, but there is room for error due to the fact that it is hard to observe a color change when the flame itself is an orange tint. Through the cobalt glass there appeared to be “no color”. The following cation logic tree was derived by analyzing the observations of each…show more content… When one drop was added to the chloride anion a cloudy and mucus-like precipitate forms. The carbonate anion experienced the same results as that of the chloride anion. In contrast the nitrate and sulfate anions did not form a precipitate. When three drops of 6 M of 〖"HNO" 〗_"3" was added to the chloride anion containing the precipitate, bubbling occurred and white specs appeared on top of the solution. The carbonate anion experienced a heavy concentration of bubbling that ceased after drops .Following the process of making the chloride solution more acidic for the chloride confirmation test, five drops of silver nitrate were added that resulted in the formation of a white, cloudy, solid precipitate. After centrifuging the solution, the white precipitate collected on the edge of the tube. Ammonium hydroxide was added and dissolved the precipitate. When 6 M of 〖"HNO" 〗_"3" was added to the solution, the precipitate re-formed which confirmed that chloride was present. The sulfate test required two drops of 〖"HNO" 〗_"3" to make the sulfate solution acidic. As instructed by the lab manual drops of 0.1 〖"BaCl" 〗_"2" were added to the solution. Although the precipitate was evident after a single drop, an additional drop was added that increased the amount of precipitate significantly. Following the instructions for the nitrate test
