Silver is used in making mirrors.(A) True(B) False

Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity and reflectivity to any metal. So, now try to figure out if silver is used in making mirrors. Complete step by step answer: >Let us first know about silver. - Silver is widely distributed in nature, but the total amount is quite small when compared with other metals; the metal constitutes0.05 part per million of Earth’s crust. - Most silver is derived as a by-product from ores that are mined and processed to obtain these other metals. - The metal does not react with moist air or dry oxygen but is oxidized superficially by moist ozone. It is quickly tarnished at room temperature by sulfur. > Now, let us see the reactivity of silver metal. - Many metals have good reflection of light. The reason silver is used among other different metallic materials is due to its high theoretical reflectance of up to 95% in the visible light wavelength region and its ability to form a smooth coating. Hence, Silver is used for making mirrors due to its high reflectivity property. So the given statement is true, option A is the required answer. Note: In lead frame industries, the lead frame substances will be pretreated chemically to obtain a smoother surface. After which highly silver coating will be electrodeposited on the substrate with the aid of suitable brighteners and wetting agents.
