It is a white, water-soluble solid that is used in a variety of applications, including photography, as an antichlor, and in the textile industry.<\/p>\n<p>In photography, sodium thiosulfate is used to fix the image on photographic film or paper. It does this by converting the unexposed silver halide crystals into silver sulfide, which is a black precipitate that is not soluble in water. This prevents the unexposed silver halide crystals from being developed into an image.<\/p>\n<p>Sodium thiosulfate is also used as an antichlor. Chlorine is used in the textile industry to bleach fabrics. However, the chlorine can also react with the natural oils in the fabric, causing them to become brittle and discolored. Sodium thiosulfate can be used to neutralize the chlorine, preventing these problems.<\/p>\n<p>In addition to its uses in photography and as an antichlor, sodium thiosulfate is also used in a variety of other applications, including:<\/p>\n<ul>\n<li>As a reducing agent in the production of other chemicals<\/li>\n<li>As a mordant in the textile industry<\/li>\n<li>As a fire retardant<\/li>\n<li>As a food additive<\/li>\n<\/ul>\n<p>Sodium thiosulfate is a safe and effective chemical that has a wide range of uses. It is important to note, however, that sodium thiosulfate can be toxic if ingested in large quantities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Chrome red&#8221; option2=&#8221;Sodium thiosulphate&#8221; option3=&#8221;Hydrogen peroxide&#8221; option4=&#8221;Calomel&#8221; correct=&#8221;option2&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19],"tags":[],"class_list":["post-2275","post","type-post","status-publish","format-standard","hentry","category-chemistry","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 one of the following substances is used in photography and also as an antichlor ?<\/title>\n<meta name=\"description\" content=\"Sodium thiosulfate is a chemical compound with the formula Na2S2O3.
