What is sodium thiosulfate pentahydrate used for?
Sodium thiosulfate is used in gold mining, water treatment, analytical chemistry, the development of silver-based photographic film and prints, and medicine. The medical uses of sodium thiosulfate include treatment of cyanide poisoning and pityriasis.
What is the molarity of sodium thiosulfate?
0.1M sodium thiosulphate means 0.1 moles of the compound has been dissolved in 1 liter of water to form the solution. This implies that 15.8 g of sodium thiosulphate is dissolved in 1 liter of water to make 0.1 M solution of it.
How do you find the molecular weight of sodium thiosulfate?
To calculate the molar mass of sodium thiosulfate, Na2S2O3 , we need to find all the molar masses of the elements, and add them together. Na has a molar mass of 23 g/mol . So, Na2 will have a molar mass of 23 g/mol⋅2=46 g/mol .
What is the mass of carbon dioxide co2?
44.01 g/mol
Carbon dioxide/Molar mass
How is sodium thiosulfate pentahydrate made?
In the laboratory, this salt can be prepared by heating an aqueous solution of sodium sulfite with sulfur or by boiling aqueous sodium hydroxide and sulfur according to this equation: 6 NaOH + 4 S → 2 Na 2S + Na 2S 2O 3 + 3 H 2O.
What elements are in sodium thiosulfate pentahydrate?
Sodium thiosulfate pentahydrate is a hydrate consisting of sodium thiosulfate with 5 mol eq. of water.
What is the molarity of s2o32?
Explanation: If no reaction takes place (which is true in the case noted), you’re simply diluting the concentrate to (30/35)th of it’s original concentration to give a 3035×0.162M = 0.139M Solution of Na2S2O3 .
What is the mass of 5H2O?
249.68 g/mol
