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...
Suppose a student needs to standardize a sodium thiosulfate, Na, S,Og, 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 KIO2 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 concentration of Na,...

The student adds a 1.00 mlL 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...
A 25-mL aliquot of a 0.0104 M KIO, solution is titrated to the end point with 17.27 mL of a sodium thiosulfate, Na,S,O3 , solution using a starch-iodide indicator. What is the molar concentration of the Na,S,O, solution?
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. Calculate the concentration in mol/L of the chemist's sodium thiosulfate solution. Round your answer to 3 significant digits. moll. X $ Explantion Check
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 201.mg of oxalic acid H2C2O4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 63.0mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide...

3. A student followed the procedure of this experiment to determine the percent Nauha commercial bleaching solution that was found in the basement of an abandoned house. The student diluted 50.00 mL of the commercial bleaching solution to 250 ml in a volumetric flask, and titrated a 20-ml aliquot of the diluted bleaching solution. The titration required 35.46 ml of 0.1052M Na,s,o, solution. A faded price label on the gallon bottle read $0.79. The density of the bleaching solution was...
