Unformatted text preview: density and a minimum deviation. Preciseness was the most important. The more precise the measurements, the closer the average would be to those measurements. This would account for a small deviation which is what is wanted. Most measurements in the lab were repetitive. This helped to make sure the deviations were minimal. The buret and pipet were used a fair amount in this lab, this lab explained the correct techniques for using them and any safety procedures which are critical in a lab. The analytical balance is much more precise than the top loading balance. This gave a clear precise reading so that we could be very sure about the weight of the solution, crucible and cover on the crucible. This accuracy leads to good accuracies in the calculations to find density. Also proper techniques for being safe in the lab were discussed and that was very helpful....
