Question

Suppose your percent yield for the recycling aluminum were 22% (ie, less than 100% yield): Identify two sources of error that could contribute to this lack in mass of your product. a. b. Identify ways to prevent those sources of error. How would those sources of error affect the melting point range of your final product? Explain why. c. uppose your percent yield for the recycling aluminum were 178% (ie. more than 00% yield): Identify two sources of error that could contribute to this increase in mass of your product. Identify ways to prevent those sources of error. How would those sources of error affect the melting point range of your final product? Explain why a. b. c. mass mol

Explanation / Answer

for less than 100% error

a) the reasons for lack of mass can be:

instrumental error like weighing machine which is not calibrated properly and

manual error error like loss of substance during transfer of the sample.

b) instrumental error can be decreased by calibrating the weighing machine and time to time analysing its efficiency.

manual error can be reduced by using proper apparatus like funnel to transfer the substance and properly analysing the transferred mass correctly.

c) These errors would not change the melting point as melting point is an intensive property that which depends on nature of substance rather than amount of substance.
