It is a moderate reducing agent. It is a source of thiosulfate ion (S2O3-2) (dissolves silver salts). Its major use is as a fixing agent in photography for developing film and the extracting silver from ore. It is used in chrome-tanning leather and in chemical manufacture as a source of sulfide ion. It is also used in paper, textile, and water treatment industry and gas purification.\u003c\/p\u003e\n\u003ch3\u003eSales Specification\u003c\/h3\u003e\n\u003cp\u003eAppearance : Colorless Transparent\u003cbr\u003ePurity:  ≥99.00%\u003cbr\u003eInsoluble substance in water:  ≤0.01%\u003cbr\u003eSulphide:  ≤0.001%\u003cbr\u003eFe:  ≤0.001%\u003cbr\u003ePH(Solution concentration 20%) :6.5~9.5\u003cbr\u003eParticle size\/GRAM : 12~16\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003ch3\u003ePacking\u003c\/h3\u003e\n\u003cp\u003e55.12 lb paper bag\u003c\/p\u003e","brand":"Wintersun Chemical","offers":[{"title":"Default Title","offer_id":41603173875779,"sku":"19-125-01","price":198.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/7981\/files\/19-125-01PRINTEDBAG.jpg?v=1780936313","url":"https:\/\/www.wintersunchemical.com\/products\/sodium-thiosulfate-pentahydrate-na2o3s2-5h2o-cas_10102-17-7-food-grade-99-solid-55-lb-bag","provider":"Wintersun Chemical","version":"1.0","type":"link"}
