Do you mean errors?

If so in general for gravimetric analysis:


a.   Incomplete precipitation results in a value for the percentage of analyte in the sample that is too low.
b.   Incomplete drying of the sample results in a value for the percentage of analyte in the sample that is too high
c.   Other ions in the sample may also be precipitated resulting in a value for the percentage of analyte in the sample that is too high
