(a)
Interpretation:
State that the copper element A or element B is labeled in given phase diagram of copper-silver metals.

Concept Introduction:
The properties of the copper-silver alloy are as follows-
1. Melting point −
2. Molecular weight −
3. Density −
4. Insoluble in water
In the case of silver and copper alloy, both of these are not able to melt together and form a new alloy with
1. Sterling silver − In sterling silver, the weight percentage of pure silver is
2. Coin silver - The weight percentage of pure silver available in coin silver is
There is a new alloy also available known as Electrum. In this alloy, the weight percentage of silver is from
(b)
Interpretation:
The well labelled phase diagram of the copper silver alloy needs to be sketched.

Interpretation:
The statement "microstructure can lead to the discrepancy" needs to be justified by giving an example.
