Question

Which metal foil is used for packing some of the medicine tablets?
A. Copper
B. Zinc
C. Aluminium
D. All of the above

Answer 1

Hint: Packaging is a vital component within the development of varied drug formulations in the pharmaceutical industry. Packaging of pharmaceutical dosage forms incorporates a close relationship between a pharmaceutical preparation and its package which could be a major concern to the drug stability and safety. The choice of the Packaging material is formed on the idea of its efficacy and performance characteristics in preserving the standard, potency, and safety of the pharmaceutical products.

Complete step by step answer:
Aluminium could be a very useful material used for various purposes, and one in all such important purposes is to be used as foils for medicines.
It is light, flexible, and versatile which makes it an ideal material for using as a medical foil to stay the medicines safely. This is due to its peculiar properties.
Its density is non-toxic, has high thermal conductivity, has excellent corrosion resistance, and maybe cast, machined, and molded quickly. It’s non-magnetic and non-sparking additionally. It's the second most ductile and therefore the sixth most malleable metal. Aluminium could be a metal that is flexible and light-weight. Because of a skinny film of oxidation that happens rapidly because it is exposed to sunlight, it's a dull silver look.
Aluminium is non-toxic, non-magnetic, and non-sparking (like metal). Aluminium only has one isotope that exists naturally, which isn't radioactive. Pure aluminium ($\,99.996\% \,$) is sort of soft and weak; commercial aluminium ($\,99 - 99.6\% \,$ pure) with small amounts of silicon and iron is difficult and powerful.
Ductile and highly malleable, aluminium is often drawn into wire or rolled into thin foil. The metal is simply about one-third as dense as iron or copper. Though chemically active, aluminium is nevertheless highly corrosion-resistant, because in the air a tough, tough oxide film forms on its surface. Aluminium may be a very useful material used for various purposes, and one of such important purposes is to be used as foils for medicines.
The foil roll is proof against water and plenty of chemical components. Combining materials with the foil makes it opaque and thus, protects sensitive products from light exposure.

So, the correct answer is Option C .

Note: Aluminium metal is obtained from the pure hot molten $\,A{l_2}{O_{3\,}}\,$ by an electrolytic method. The electrolysis of the recent oxide in a very carbon lined steel cell acts because the cathode with carbon anodes is the most typical method. Most common uses of aluminium are: - cans and foils - kitchen utensils - Residential house siding - Industrial applications where a robust, light, easily material is required - Wire for electricity, although its electrical conductivity is simply about $\,60\% \,$ that of copper per area of cross-section, it's utilized in electrical transmission lines due to its lightness and price - Alloys are of important importance within the construction of recent aircraft and rockets
