Ok, so I'm sure many of you have heard of this lab. The instructor hands out 9 unknown solutions, and it's your goal to label each. The names have been given to us a day before and we are allowed to research the elements. The list of elements include: BaCl2; Cu(NO3)2; CuSO4; HCl; Hg2(NO3)2; KNO3; K2CrO4; AgNO3; and Na2S So far I've gathered that: Barium Sulfate will be a thick white precip. Barium Chromate is yello Copper (II) Nitrate is blue crystals, when hydrated Copper (II) Sulfate is a blue power, when hydrated Potassium Chromate is bright yellow, red cloud with Ag, Brown with Cu, and a yellow precip. will form with Barium. Also that AgNO3 is colorless I need help finding ways to mix these to figure out their identities, with as little mixes possible, and only the aqueous solutions are available to us, with watch glasses THE LAB IS TOMORROW AND I NEED A PRE LAB. Please help.
