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....

Periodic Trends in Group
II
Objective
In this experiment, the trend in one of the several periodic
properties for group II of the Periodic Table will be
determined.
Introduction
Elements in the same group of the Periodic Table have similar
chemical and physical properties that gradually change as one goes
from one element in the group to the next. By observing the trends
in properties, the elements can be arranged in the order in which
they appear in the Periodic...
