Hint: Etching is described as the process of creating art or designs on plates or other objects using the corrosive action of an acid.
Complete answer:
Firstly we should evaluate each of the options given in the question and then we found that the correct answer is option D-\[HF\].
Etching is a technique for creating patterns on plates or other surfaces. The material must be corroded by an acid in order to create the artwork.
Let's take a look at how this works:
-Sand, which is mainly silicon dioxide, is used to make glass.
This sand is heated until it melts and becomes liquid.
-This liquid sand is later used to make glass.
Now we'll look at the glass etching process:
- To begin, a layer of beeswax or paraffin is applied to the glass, which is then traced with metal needles to create designs or patterns.
The glass is then dipped in a hydrofluoric acid solution (\[HF\]). It etches the designs or patterns into the protective coating layer through the grooves created by the needles. The following is the etching of glass reaction:
\[4HF\, + Si{O_2} \to Si{F_{4(g)}} + 2{H_2}O\]
The use of \[HF\] (hydrofluoric acid) in glass etching is due to the creation of a strong bond between the fluoride anions and the silicon molecules present in the glass.
Note:
Since it can quickly dislocate oxygen from silicon dioxide, \[HF\](hydrofluoric acid) is the only compound that can etch through the glass, while \[HCl,{\text{ }}HN{O_3},\] aqua-regia does not react with the glass. As a result, we can safely store acids in glass containers.
