<span>Silver is usually alloyed with copper to increase the
hardness and strength of sterling silver. Pure silver is relatively soft and
prone to tarnishing so other metals like those that copper is used to reduce
tarnishing and act as a solute in sterling silver. Copper is usually soluble in
most solvents.</span>
3KI + HClO + HCl = 2KCl + K[I₃] + H₂O
10FeSO₄ + 2KMnO₄ + 8H₂SO₄ = 5Fe₂(SO₄)₃ + 2MnSO₄ + K₂SO₄ + 8H₂O
Solvent is used to dissolve the solute in the solution
CUSO4 is an example of A COMPOUND.
A compound is the product formed when two or more elements chemically combine together to form a new product or products, which are quite different from the reactants. The elements in the compound are usually combined together in a specific ratio. In the question given above, CUSO4 is a compound because, copper, sulphur and oxgyen had combined together chemically to form a new compound, which is CUSO4. The ratio of combination is 1:1:4, that is, one atom of copper combine with one atom of sulphur and four atoms of oxygen to form one molecule of CUSO4.
