A student determined the concertration of NaOCI in a commercial bleach sample using the same technique described in section "F" of the Halogens and Their Compounds lab. The student required 18 drops of 0.01M Na25203 to reach the end point. What is the concentration (reported in percentage) of NaOCI in the bleach sample?
In order to adjust the Potassium Permanganate solution, 0.0544g Na2C2O4 was taken and necessary experimental procedures were performed on it and the titrant consumption was found to be 7.9 mL. What is the KMnO4 concentration?
The Tl in a 9.76-g sample of rodenticide was oxidized to the trivalent state and treated with an unmeasured excess of Mg/EDTA solution. The reaction is Tl+3 + MgY-2 → TlY- + Mg+2 . Molecular mass: Tl2SO4 = 504.8 a. Titration of the liberated Mg2+ required 13.34-mL of 0.03560 N EDTA. The type of titration involved in the assay is (direct/indirect/residual) ______? b. percentage of Tl2SO4 in the sample is __________ %?
An unknown sample weighing 1.5098 g was acidified with 3.0 M H2SO4 to dissolve the copper compounds and diluted with 30 mL distilled water. This was followed by the addition of excess KI producing I2 and CuI precipitate from Cu2+ (Reaction 1). Then, the liberated I2 reacted with the excess KI forming triiodide anion (Reaction 2), which was then titrated with Na2S2O3 titrant (Reaction 3). This entire solution required 17.60 mL of the titrant to reach the starch end point. What are the balanced chemical equations for reactions 1-3? What is the mole ration between Cu2+ and S2O32-?
Gravimetric Analysis. Please include complete solution, thank you. 4.) A 0.2025 g sample consisting of only BaCl2 and KCl required 20.25 mL of 0.1200 M AgNO3 solution for the quantitative precipitation of chloride. Calculate the %Ba and %K in the sample.
In the titration of MgSO4.2H2O (2g per litre) against a 0.01 M solution of the disodium salt of ethylenediamine tetraacetic acid (EDTA) the titres obtained were as follows ; titre 1: start - 0.7 ml and end - 13.3 ml (12.6ml) titre 2: start - 13.3 ml and end 25.7 ml (12.4ml) The average titre is 12.5ml Q.
