Question

The alloy bronze contains Copper and Tin. This is a:
A. Homogeneous mixture
B. Heterogeneous mixture
C. Solid solution of two immiscible metals
D. Both A and B

Answer 1

Hint- In order to deal with this question first we will define the term bronze then according to its property and characteristic we will proceed further to get the required answer.

Complete step-by-step answer:
Bronze is an alloy composed primarily of copper, usually with around 12–12.5 per cent tin and sometimes with the inclusion of other metals (such as iron, manganese , nickel or zinc) and often non-metals or metalloids such as arsenic, phosphorus or silicon. These modifications produce a variety of alloys that might be tougher than just copper, or have other useful properties such as hardness, ductility, or machinability.
Bronzes are typically ductile alloys, far less porous than cast iron. Bronze usually oxidizes only superficially; once a layer of copper oxide (to eventually become copper carbonate) is formed, the underlying metal is covered from further corrosion. That can be seen on Hellenistic Period statues. Nevertheless, if copper chloride is created, a corrosion mode called "bronze disease" will inevitably kill it completely.
Hence, the alloy bronze contains Copper and Tin is a homogeneous mixture.
So, the correct answer is option A.

Additional Information- Copper and its alloys have a wide array of applications representing their flexible physical, electronic, and chemical properties. Several typical examples are the high electrical conductivity of pure copper, low friction properties of bronze bearing (bronze with a high lead content — 6–8 per cent), resonant qualities of bronze bell (20 percent tin, 80 percent copper), and corrosion tolerance of some bronze alloys by seawater.

Note- Copper-based alloys have lower melting points than steel or iron, and are made more readily from their metals. While alloys using aluminum or silicon can be marginally less dense, they are usually around 10 per cent denser than steel. Bronze is a stronger thermal and electrical conductor than most steels. In general, the cost of copper base alloys is higher than that of steels but lower than that of nickel base alloys.
