The purpose of this evaluation of quantitative experiments for general college chemistry was; first, to learn the different types of quantitative experiments used; second, to examine the methods or instructions given; third, to run a few trials to discover the range of error expected; and fourth, to determine the cause of error in some cases. It was the aim to carry out all trials as a general chemistry student would, using a good grade horn pan balance with a $6.00 set of weights. At least three trials were run to determine the expected range of error and to give a basis for determining the desirability of the method or material used. In no case are the results to be taken arbitrarily as the limit within which a student's answer must fall in order to be correct.
