Tell what effect each of the following errors would have on yourdeterminations of the percentages of the components in yourmixture. In each case for each component, indicate if the errorwould result in a determination of each substance that is too high,too low, or unchanged. EXPLAIN WHY!
a) some of the mixture splattered during the first heating (sublimation)
ammonium chloride:
salt:
sand:
b) The sublimation was stopped before all the ammonium chloridewas removed.
ammonium chloride:
salt:
sand:
c) The residue was washed with tap water instead of deionizedwater.
ammonium chloride:
salt:
sand:
d) A watch glass was not used to cover the evaporating dishduring the evaporation
ammonium chloride

sand
e)The residue from the filtration was not washed.
