Data Analysis and Extension Questions- Lab 7 1. During the analysis of the mass % of water in the hydrate, why is it necessary to heat the crucible to red heat before adding any solid hydrate? necessany to heat the crucible to remoua adhering to the surface. These con couse Potential Contaminotion and may Chonge tha 2. During the heating of the metal hydrate salt, you accidentally heated the crucible too rapidly to an extreme temperature. This caused the salt to decompose and release Oxygen gas (O2) along with the water from the salt. Would this give a higher, lower or Mass Orerall the same calculated mass % of water in the metal hydrate salt? This would Water in of the give the oer rnass.
