Sodium Thiosulfate solutions are almost exclusively used to standardize Iodine solutions or as back-titrants in titrations using Iodine. Solutions of Sodium Thiosulfate are most commonly standardized with Potassium Dichromate or Potassium Iodate solutions, which generate Iodine from Iodide. Starch indicator is typically used. The reaction with Iodine is:
Titrations with standard Sodium Thiosulfate solution are best conducted in the pH 5 - 9 range. Since this is not always possible, the titrations should be conducted rapidly and with adequate stirring to insure rapid reaction of the Thiosulfate, thus minimizing any acid-accelerated decomposition. This will also minimize the acid-catalyzed oxidation of Iodide (usually present in a titration involving Thiosulfate) to Iodate, which could lead to decreased accuracy.
Sodium Thiosulfate solutions are subject to bacterial decomposition and chemical deterioration. Sodium Thiosulfate solutions decompose in acid solution resulting in the evolution of Sulfur Dioxide gas and precipitation of elemental Sulfur. Contact with Carbon Dioxide in the air can produce the acidity leading to this decomposition, which is faster in more dilute Thiosulfate solutions.

We have copper slag in six grades from Turbo+ to HD+ with different particle size. The user has the option to choose the appropriate grade based on the cleanliness level (SA2, 2½ & 3) and anchor profile (40-120 microns) requirements.
Copper slag is most commonly used as blasting agent in heavy industries, shipyards, oil & gas companies, paint manufacturers, coating contractors, tank builders, pressure vessel fabricators, off shore yards, construction chemical manufacturers and all major industries.
Copper Slag uses:
In addition to abrasives, copper slag is also used for making abrasive tools, roofing granules, cutting tools, tiles, glass, road-base construction, railroad ballast, asphalt pavements & in the cement and concrete industries. Copper slag partially replaces aggregates in concrete, currently, more than 75% volume of concrete contains aggregates. The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries.
