Seven Solution Problem Deduction Lab This experiment is an exercise in observation and deduction, both critical skills for productive scientific study. You will be making observations on the results of binary mixing from a total of seven known solutions. From your observations and your knowledge of chemical behavior and solubility. you identify the identity of each of the nine unmarked solutions. As you can probably already see, careful observations, recording of results and deductions will be the key to success....
