Make absolutely sure you attribute this to Holly Hu, Andy Moreland and Anita Dunsmore. Not including chemical equations -- haven't worked those out yet and you can do those on your own ;-) If you can't understand anything, let me know. Feel free to re-write things for clarity/length * KI + CuSO4 Green color to yellow to orange to brown over 1.5 seconds. Fizz, bubbles, solid precipitate (prec) + AgNO3 Clear -> yellow, white precipitate, 1/2 second + Na2CO3 4 1mm diameter white flakes on bottom, clear + NaOH clear, no bubbles, slight blue tint from side +FeCl3 yellow -> brown 5secs, -> amber -> brown over next minute, cloudy *CuSO4 +AgNO3 specs on bottom, small, fizz, pale blue +Na2CO3 cloudy w/ solid white swirls marbled throughout, blue liquid +NaOH White clouds, blue liquid, opaque +F3Cl3 turns turquoise over 4 seconds, clear *AgNO3 + Na2Co3 Milky, creamy -> yellowish white, yellows over time, 100% opaque +NaOH Mocha (light brown) & white clouds over 1 second + FeCL3 white -> yellow over 2 seconds, clearish w/ granuled precipitate *Na2CO3 +NaOH dust like stuff on bottom, small (2mm diameter) flakes, clear liquid +FeCl3 white bands through opaque orange liquids, clear at bottom, red spots *NaOH +FeCL3 Golden -> orange quickly, bands of opaque redder orange precipitate |
