If the volatile impurities are not burned off the crucible and cover,how does this affect the reported percent of water
if some volatile impurities in the crecible are not burned off in step 1 but are removed in step 4 , is the reported percent mass of water in the hydrated salt too high or to low?
To determine whether the reported mass of water removed is too high or too low when volatile impurities in the crucible are removed from the hydrated MgSO4 along with the water, we need to consider the concept of volatile impurities and their effect on the measurement of water mass.
Volatile impurities are substances that have a relatively low boiling point and readily evaporate at relatively low temperatures. When the hydrated MgSO4 is heated to remove the water, these volatile impurities might also evaporate and be lost along with the water vapor.
If the volatile impurities evaporate and are lost during the heating process, it would result in a lower reported mass of water removed. This is because the mass of the volatile impurities, which were initially present in the hydrated MgSO4, would be subtracted from the measured mass of water loss. Therefore, the reported mass of water removed would be lower than the actual mass of water lost.
In summary, if volatile impurities are removed from the crucible along with the water during the heating process, the reported mass of water removed would be lower (too low) than the actual mass of water lost.
