It is important in gravimetric analysis to add an excess amount of precipitating ions to a solution containing an analyte because it helps to determine the mass of the analyte.
<h3>What is Gravimetric analysis?</h3>
This is a method which is used in the determination of the quantitative determination of the ion being analyzed(analyte) based on its mass.
Adding an excess amount of precipitating ions to a solution containing an analyte will make it easier for the mass of an analyte to be determined.
It is also important for the precipitate to be a pure substance with a definite and known composition which therefore makes it the most appropriate reason.

A substance's molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). ... By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.
Answer:
50CuS2 + 260HNO3 = 50Cu(NO3)2 + 100H2SO4 + 80N2O + 3H2O
Explanation:
there are lots of pairs on the periodic table that are both malleable and good conductors of heat , but in this case two good examples would be
- Silver (Ag) & Copper (Cu)
