What is the product when thiosulfate ions and iodine react?
2 S2O32- + I2 --> S4O62- + 2 I-thiosulfate + iodine -> tetrathionate* + iodide* -O3=-=S-S-S-S=-=O3-
What is the formula for potassium thiosulfate?
K2PbO2
What is the ionic formula of thiosulfate?
The ionic formula of thiosulfate is S2O3^2-. It contains two sulfur atoms bonded to three oxygen atoms in a linear structure.
In the reaction of sodium thiosulphate and iodine in aqueous medium the equivalent weight of sodium thiosulphate is equal to what?
The equivalent weight of sodium thiosulfate in the reaction with iodine is equal to its molar mass divided by the change in oxidation state of sulfur during the reaction. Since sulfur in thiosulfate changes from +6 to +2 during the reaction, the equivalent weight would be the molar mass of thiosulfate divided by 4.
What is the oxidation state of S in S2O32?
The oxidation state of sulfur in S2O32- is +2 because each oxygen has an oxidation state of -2 and the overall charge of the molecule is -2. This means that the two sulfur atoms in S2O32- must have an oxidation state of +2 each in order to balance out the negative charge.

What is the formula for potassium thiosulfate?
K2PbO2
What is oxidation state of S in S in S2O32?
The oxidation state of sulfur in a thiosulfate ion is + 2.
What is the ionic formula of thiosulfate?
The ionic formula of thiosulfate is S2O3^2-. It contains two sulfur atoms bonded to three oxygen atoms in a linear structure.
What is the balanced chemical equation for the reaction between hypochlorite ion and thiosulfate ion?
The balanced chemical equation for the reaction between hypochlorite ion (OCl-) and thiosulfate ion (S2O3^2-) is: 2OCl- + 2S2O3^2- -> 2Cl- + S4O6^2- + 2OH-
In the reaction of sodium thiosulphate and iodine in aqueous medium the equivalent weight of sodium thiosulphate is equal to what?
The equivalent weight of sodium thiosulfate in the reaction with iodine is equal to its molar mass divided by the change in oxidation state of sulfur during the reaction. Since sulfur in thiosulfate changes from +6 to +2 during the reaction, the equivalent weight would be the molar mass of thiosulfate divided by 4.
What will happen when bromine reacts with sodium thiosulphate?
When bromine reacts with sodium thiosulfate, the bromine will oxidize the thiosulfate ion to form sulfate ions and release bromide ions. This reaction can be used as a redox titration method to determine the concentration of bromine in a solution.
What is the oxidation state of S in S2O32?
The oxidation state of sulfur in S2O32- is +2 because each oxygen has an oxidation state of -2 and the overall charge of the molecule is -2. This means that the two sulfur atoms in S2O32- must have an oxidation state of +2 each in order to balance out the negative charge.
Is sodium thiosulphate used in photography?
Photographic fixing agent. An emulsion of sodium thiosulfate (called hypo by photographers) is used to stop development of exposed film. Thiosulfate converts undeveloped silver bromide grains in the film into water-soluble silver thiosulfate complexes that can be removed when the film is washed.S2O32- + AgBr(s) AgS2O3- + Br-S2O32- + AgS2O3- Ag(S2O3)23-Thiosulfate is also an antidote for cyanide poisoning. It reacts with cyanide to produce sulfite and thiocyanate ions:CN- + S2O32- SCN- + SO32-This reaction is catalyzed by an enzyme produced by cell mitochondria to neutralize small quantities of ingested cyanide (which occurs naturally in cassava root, lima beans, and almonds!).
Is the reaction between sodium thiosulfate and dilute hydrochloric acid a redox reaction?
Yes, to be more precisely: it is an acid stimulated decomposition by auto-redox or intern (self)-redox (+2,+2)S2O32− (aq) + 2 H+ (aq) --> (+4)SO2 (g) + (+0)S (s) + H2O oxidation value are superscripted prefixes between round brackets
Does potassium iodide react with sodium carbonate?
Yes, potassium iodide would react with sodium carbonate to form potassium carbonate and sodium iodide. This reaction is a double displacement reaction where the cations and anions are exchanged between the compounds.
What is the formula for thiosulphate radical?
The chemical formula for thiosulfate radical is S2O3^2-. It consists of a central sulfur atom bonded to three oxygen atoms in a trigonal planar arrangement.
