Reactions are manifested by the disappearance of properties characteristic of Copper and the appearance of new properties in the new substance or Compound.
A systematic error may have occurred at this step if the balance that was used to weight the copper was not calibrated correctly, or if the amount of copper weighed was not exactly the 0.
Copper and Water Reaction Copper does not react with water. Experience in standard chemical techniques: filtration and quantitative transfers. Although the lab was concisely outlined, there are several key elements that needed to be addressed as to diminish the amount of errors seen throughout this lab.
The substances initially involved in a reaction are called reactants or reagents. Copper in moist air slowly acquires a dull green coating because its top layer has oxidised with the air.
When sulphuric acid was added to remove any unreacted zinc, a new compound, zinc II sulphate, was produced since zinc is above hydrogen on the activity series. We have seen this reaction before in the copper chloride lab.
The Ostwald process is a chemical process for producing nitric acid, which was developed by the German chemist, Wilhelm Ostwald —
