Answer to Question #131769 in Inorganic Chemistry for Ashraf Ali

Question

2) if we are given metalic sample containing copper than:
a) How do you estimate the Cu gravimaterically??
b) What are qualitative measures used to find Cu in given sample??

Answer 1

Gravimetric determination of copper is most precise. Contemporary analytical balances helps to accurately determine the mass of the given sample. The following analysis will ensure copper is obtained from the metallic sample provided. Nevertheless, obtaining a fully pure copper metal with the exact composition represented by a chemical formula may tend to be difficult. The gravimetric methods are subject to certain degree of errors and the reason it tends to be impossible to alive at pure copper.

However, SPAMT-Test tool can be used to determine the quality of the metal. In the process, the corrosion of the potential metal versus time will be established. A drop of a conducive solution measured with a reference electrode can be used to measure the extent in which the obtained copper metal has corroded. With the help of the SPAMT-Test, the element present in the sample metal as well as its composition will be easy to determine.
