Experimental Sources of Error

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

You used 25.0 ml of KI, 48.0 ml of KNO3, 25.0 ml of( NH4)2S2O8 along with 1.0 ml of Na2S2O3 to go along with 1.0 ml samples of Na2S2O3 after each color change. Which of the solutions listed will have the biggest source of error in your readings if the solution is off by even 0.1 ml?

Please provide detailed explanation. Thanks!

Solution Preview

The smaller the total volume of each solution used, the greater the error will be when you read erroneously. So it's either KI or (NH4)2S2O8 both which have the same smallest total volume. Between these two ...

Solution Summary

The effect of reading volume incorrectly is explained.
