In an analytical laboratory that analyzes BOD, the titrant solution of sodium thiosulphate must be standardized every 3 days. The standardized concentration can be determined with the help of a standard potassium dichromate solution. This is an oxidation and reduction reaction, as well as "lodometric reaction". The reactions of the process are: 6 KI + 14 HCI + K,Cr,0,- 2 CrCl, + 3 2 + 7 H,0 + 8 KCI 2 Na,s,0, +1,- Na,s,0, +2 Nal Given the standardization data in the table below, determine the missing values as indicated by the question mark.

50 mL of a 1.067 M solution of HCI was diluted to 250 mL. The diluted HCI solution was then titrated with an unknown concentration of KOH. It is found that an average volume of 24.20 mL of KOH is required to reach an endpoint in a titration with 25.00 mL of the dilute acid solution. The equation for the reaction is; H(aq) + OH(aq) →→> H₂O (1) The concentration of KOH is 0.2205 M Calculate the concentration of the KOH in g/L (you will need to find the formula weight of KOH to do this) 15| ΑΣΦ ? g/L
A 50.0 mL solution of Ca(OH)₂ with an unknown concentration was titrated with 0.340 M HNO₃. To reach the endpoint, a total of 26.0 mL of HNO₃ was required. Write the balanced chemical equation based on the following description: aqueous calcium hydroxide reacts with aqueous nitric acid to produce the aqueous calcium nitrate and liquid water.
A sample of battery acid is to be analyzed for its sulfuric acid content. A 1.00-mL sample weighs 1.256 g . This 1.00-mL sample is diluted to 250.0 mL, and 10.00 mL of this diluted acid requires 34.89 mL of 4.522×10−3 M Ba(OH)2 for its titration. What is the mass percent of H2SO4 in the battery acid?

An iron ore was analyzed by dissolving a 2.9912-g sample in concentrated HCl. The resulting solution was diluted with water, and the iron(III) was precipitated as the hydrous oxide Fe203-XH2O by the addition of NH3.

0.3456 g of a solid acid is dissolved in 50 mL of water in a flask and a few drops of phenolphthalein are added to the solution. A buret containing 0.2545 M NaOH is prepared with an initial volume of 10.50 mL. The acid is accidentally titrated with the base beyond the end point, so 1.52 mL of 0.187 M HCl are added to the flask. The titration with the base is continued to a final volume reading of 40.55 mL. Calculate the molar mass of the solid acid.
