Powders-2

Guiding Questions: What are the methods that are used by forensic scientists to determine the nature of an unknown substance (like a white powder)? How might this lab be helpful in preparing you for the mission?

My Answer: The methods that we used were observing with a lens, added acidic acid then observing what happened, then seeing what happens when put on a hot plate, then addition of water, then adding sodium carbonate, and the last method was the addition of Lugol's solution.  Also if we find powders during the mission and need to compare the powders to the powder found at the scene of a crime then we will use the methods we learned to figure out what type of powder was left at the crime.
