Title : Determination of chemical formula of hydrate Aim To determine the chemical formula of hydrated Copper (II) sulphate, CuSO4 Research Background “When the chemical is heated the hydrate will convert to an anhydrous ionic compound (this means the water will leave it). The moles of H2O will be determined by assuming the amount of mass lost by heating is the mass of the evaporated H2O. The moles of the CuSO4 (the white substance after heating) can be calculated from the mass of the white crystals. Using the molar ratio of moles of CuSO4 to moles of H2O, one can determine the chemical formula of the hydrate.” Apparatus and materials Apparatus and Materials used Quantity Crucible and lid Tripod stand Clay triangle Wire gauze White tile…show more content…
The blue colour of hydrate CuSO4 turns white at the end of the heating process. Base of the crucible becomes black, indicates that there is soot produced. Determine The Precision Of Data by Calculating Mean or average of the data, x ̅ =(total reading)/(number of reading) Mean, x ̅ (Mass of H₂O in the hydrated sample 1 g)
