Question

A student dried a wet crucible with a kimwipe. A piece of kimwipe was left clinging to the inside wall of the crucible. The student did not see the piece of kimwipe when adding the NaHCO3-KCl mixture to the crucible. The crucible and its contents were weighed and subjected to three heating cooling cycles. Could this experimental error significantly affect the percentage of NaHCO3 in the mixture? A student dried a wet crucible with a kimwipe.

Explanation / Answer

Actually it depends on the pices of kimwipe. If its too bigger it effects the percent calculation of NaHCO3 .IF its smaller it may be ignorable. If its smaller over the range of +/- 0.001 g it shouldn't be considerable in the calculation of % error.

if its 0.1 g it contributes it weight in the calculations. But in general the regular usage kimwipes ae not that much weight and it may not effects to % calculation of NaHCO3
