Make a concentrate by adding just 4 Oz of the Sodium Thiosulfate to 1 gallon of water. Then just use 1 – 2 drops of your concentrate per gallon of water to be dechlorinated. * Always test water using a chlorine test kit to verify your chlorine activity after dechlorinating.Iodometry In analytical chemistry, sodium thiosulfate is used for the determination of the strength of a given solution of iodine. Sodium thiosulfate is preferred in iodometric analysis due to the fact that sodium thiosulfate is oxidized by iodine. Photographic Processing Sodium thiosulfate is also used as a fixer in photography. The negative plate or film obtained at the end of photographic development with a reducing agent (i.e., potassium ferrous oxalate, pyrogallol) contains AgBr which has not been light-activated and reduced to Ag metal. This is treated with sodium thiosulfate solution so that AgBr is removed as a soluble complex compound. This process is known as “fixing” of the negative plate or film.Our Chemical Products are shipped with current Safety Data Sheets and Labeling The manufacturer and seller make no representation or warranty, including merchant ability expressed or implied.
