2. A 0.2586 g sample contains only pure Na,C,04 ( MW = 134.00) and pure KHC04 (MW = 128.13). It required 48.39 mL of 0.01660 M KMNO, for titration to the equivalence point in an acid solution where the MnO4 was reduced to Mn2* and the C0,²- oxidized to CO2. How much KHC204 was present in the mixture?

Explain the reason for the need for KI in the preparation of these solutions?
Potassium dichromate has several industrial applications. To determine the purity of the salt that will be used in different industrial processes, a sample mass equal to 2.660 g was dissolved and quantitatively transferred to a 500.00 mL flask. An aliquot of 25.00 mL of this solution was treated with excess KI and the released iodine was titrated with 0.1000 mol L-1 sodium thiosulfate, spending 27.00 mL. Calculate the purity of the analyzed salt. Data:K = 39.10 O = 16.00 Cr = 52.00 I = 126.9 S = 32.07

A potentiometric titration was done using a solution containing 200 mL of water, 20 mL of 3 M sulfuric acid, 5 mL of concentrated phosphoric acid and 10.00 mL of 0.5964 N K2Cr2O7. The amount of titrant added was 19.24 mL of 0.3355 N Fe2+ solution. [H+] = 1.41 x 10-3 M during the titration. Find the concentrations of all species relevant to the redox chemistry present in solution at this point in the titration.
What is the concentration of ions in the soil solution after fertilizer application? Suppose that 122 pounds of K+ were applied per acre, then a gentle rain soaked the top 10 inches of soil to field capacity, which for the given soil was about 16% water by volume. If the K+ was applied as KCl, it is plausible that it all dissolved and distributed relatively uniformly with the infiltrating water. If so, then what was the K+ concentration in the soil solution in mol K+/L solution? Note that the volume can be computed like we do for an acre-furrow-slice (AFS), as area times depth. This is going to be a relatively small number, so please report your answer in mol K+/L solution to at least 5 decimal places.
