Quizplus · Accepted Answer

Hydrofluoric acid is commonly used for etching and frosting glass as it reacts with the silicon dioxide present in the glass, creating a rough surface. Other acids, such as hydrochloric acid and nitric acid, may also be used for glass etching, but they are less commonly used and may not provide the same degree of etching or frosting as hydrofluoric acid. Hydrobromic acid is not typically used for glass etching or frosting.
