Manganese dioxide<\/strong><\/p>\n<p>Manganese dioxide is a chemical compound with the formula MnO2. It is a black or brown solid that is used in a variety of applications, including glassmaking. In glassmaking, manganese dioxide is used to remove the green color from glass. This is because manganese dioxide reacts with the iron in the glass to form a black compound that does not absorb visible light. As a result, the glass becomes clear.<\/p>\n<p>Silicon dioxide (SiO2), titanium dioxide (TiO2), and sulfur dioxide (SO2) are not used to remove the green color from glass. Silicon dioxide is the main component of sand, and it is used in glassmaking to provide strength and durability. Titanium dioxide is a white pigment that is used to make glass white. Sulfur dioxide is a gas that is used in glassmaking to remove impurities from the glass.<\/p>\n<p>Manganese dioxide is the only option that is used to remove the green color from glass.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Silicon dioxide&#8221; option2=&#8221;Titanium dioxide&#8221; option3=&#8221;Sulphur dioxide&#8221; option4=&#8221;Manganese dioxide&#8221; correct=&#8221;option4&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[638],"tags":[],"class_list":["post-5565","post","type-post","status-publish","format-standard","hentry","category-chemistry-in-everyday-life","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Which of the following is used to remove the green colour from glass?
