Scenario: You work in a lab that tests soil samples for heavy metals. When you came in to your lab today, there was some white solid that had been spilled on the countertop next to the sink. You also observe that there is a ring of clear, colorless liquid in the middle of the white solid. Over to the right are a number of containers that had been used recently. These containers contain chemical compounds, in solid form, that are commonly used in your lab.
They are:
1. Barium sulfate (BaSO4)
2. Sodium thiosulfate (Na2S2O3)
3. Sodium chloride (NaCl)
4. Potassium nitrite(KNO3)
5. Iron (III) nitrate (Fe(NO3) 3)
6. Sucrose (C12H22O11)
7. Lithium Sulfate (Li2SO4)
8. Naphthalene (C10H8)
9. Potassium permanganate (KMnO4)
10. Copper (II) chloride (CuCl2)
For the purposes of this assignment, it is assumed that the spilled solid is homogenous. Your question is “What is the white solid?”
