1. Based on the procedure of this experiment, explain the effect of the following actions on the
2
measured masses of the components indicated. Where indicated, also address the effect on
he percent recovery. The choices include: lower, higher, no effect or could be higher or
lower. If the answer could be higher or lower, provide a detailed explanation.
a) Sublimation of NH4C1 was not complete. How does this situation affect the measured
mass of NH4CI and the percent recovery?
b) While decanting, some of the salty water was spilled onto the lab bench. How does this
situation affect the measured mass of NaCl and the percent recovery?
C) While decanting, some of the sand was inadvertently transferred to the second
evaporating dish. How does this situation affect the measured masses of NaCl and SiO2
and the percent recovery?
d) While weighing the first evaporating dish after subliming the NH4C1, the balance was not
properly set to zero prior to the measurement. How does this situation affect the
measured mass of NH4C1?
e) While drying the NaCl, some of the solution splashed onto the watch glass causing salt to
deposit
on the watch glass. How does this situation affect the measured mass of NaCl?
f) While drying the sand, formation of steam caused some the sand to eject out of the
container and onto the lab bench. How does this situation affect the measured mass of
SiO2 and the percent recovery?

Step 1

Hello. Since you have posted multiple questions and not specified which question needs to be solved, we will solve the first question for you. If you want any other specific question to be solved then please resubmit only that question or specify the question number.

It is given that the sublimation of NH4Cl was not complete. As a consequence, the sublimation was not finished. At this point you have two alternatives; after sublimation, it could imply that either the sublimated part is being weighted or the rest of the substance. In the former case, at that point, your outcomes are lower than they could be. If it is the subsequent case, and you are isolating the objective substance from NH4Cl, with its sublimation, at that point the mass you acquire will be higher than it ought to be, thinking of it still having NH4Cl. The percent recuperation of mass will be higher, yet the immaculateness will be less.

Step 2
  1. b) By decanting, it is intended that a large portion of the fluid is lost that contains certain substances; for this situation, salt. In any case, in the event that some salty water has been spilled, at that point the mass of salt, at last, will be short of what it ought to be. This is on the grounds that the spilling of the blend infers that some salt has been lost there. Percent recuperation will likewise be lower due to presence of less mass than there was initially.
Step 3
  1. c) If some sand was moved after decantation, it will change the mass. The outcome will be higher in mass since sand is incorporated after decantation. Recuperation ma...
