A chemist must prepare 700.mL of 2.00M aqueous sodium thiosulfate Na2S2O3 working solution. He'll do this by pouring out some 3.15mol/L aqueous sodium thiosulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the sodium thiosulfate stock solution that the chemist should pour out. Round your answer to 3 significant digits.
If you have 275 mg of sodium thiosulfate in 20 mL of water, and 14.8 mL of this solution was required to titrate 104 mg of iodine in 20 mL of solution, what is the amount in mg of Na2S2O3 that is required to completely reduce the 104 mg of I2?
In one trial of the standardization of a Na2S2O3 solution, a 10.00 mL volume of 5.00×10-3 M KIO3 is pipetted into a 250 mL Erlenmeyer flask. The solution is titratedto the endpoint with 15.23 mL of the Na2S2O3 solution. What is the molar concentration of this sodium thiosulfate solution?
Unexposed silver halides are removed from photographic film when they react with sodium thiosulfate (Na2S2O3, called hypo) to form the complex ion Ag(S2O3)23-. The reaction with silver bromide is: AgBr(s) + 2 S2O32- (aq) ⇌ Ag(S2O3)23- (aq) + Br- (aq) The equilibria that need to be considered are: Ag+ + 2 S2O32- (aq) ⇌ Ag(S2O3)23- (aq) Kf = 4.7 x 1013 AgBr(s) ⇌ Ag+ (aq) + Br- (aq) Ksp = 5.0 x 10-13 What mass of Na2S2O3 is required to...
A chemist must dilute 31.8mL of 4.67M aqueous sodium thiosulfate Na2S2O3 solution until the concentration falls to 3.00M . He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in milliliters. Round your answer to 3 significant digits.
A 10.00 ml sample of .0.0100 M KIO3 was titrated against a solution of sodium thiosulfate to standardize it. The initial buret volume reading was 0.07 ml. The final buret reading was 6.54 ml. Calculate the [Na2S2O3].
Calculating molarity using solute mass Esmeralda A chemist prepares a solution of sodium thiosulfate (Na,s,o,) by measuring out 87.1 g of sodium thiosulfate into a 150. ml. volumetric flask and filling the flask to the mark with water.

Suppose a student needs to standardize a sodium thiosulfate, Na, S, O3, solution for a titration experiment. To do so, he or she will react it with a solution of iodine. The student adds a 1.00 mL aliquot of 0.0200 M KIO, solution to a flask, followed by 3 mL of distilled water, 0.2 g of solid KI, and 1 mL H, SO . The student then titrates the solution with sodium thiosulfate solution in order to determine the exact...
