Chemistry uncertainty conical flask Essay Example

s. F. ) The result of the experiment has shown that the uncertainty of a mall conical flask is ml.

Comparing to a 100 ml volumetric flask, which has absolute uncertainty of 0. Ml, a conical flask is rather uncertain and will give inaccurate results.

This explains why a conical flask is usually used for holding chemicals (for example in titration, it is used for containing the solution being titrated against and the indicator) instead of used for giving measurements. In this experiment, an observation was that the value displayed on the balance fluctuated within 0. 0004 g. This observation was noted as it implied that even though the wind speed was kept constant around the environment (for example fans and air conditioner turned of, he movements generated by man or usage of balance had minor effect on the accuracy of the result.

The effect of these small errors on the result can be eliminated by carrying out more rounds of the experiment, or by repeating with different electronic balances. Further investigation could be done on finding the values of uncertainty of different sizes and grades of conical flasks. By repeating the experiment with different sizes and grades of conical flasks, we can gain understanding in different instruments and the result might be used as reference in future experiments involving conical flasks.
