Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the formula KHC8H4O4. This is often written in the short-hand notation as KHP. If 25.0mL of a potassium hydroxide solution are needed to neutralize 2.26g of KHP, what is the molarity of the potassium hydroxide solution? Potassium hydrogen phthalate sometimes called potassium biphthalate, as shown on this bottle is an acid that is convenient to store and use because it is a solid.
The ideal product of gravimetric analysis called precipitate should portray some specific properties. Which among the following is a property of a good precipitate and why?
A dietary iron supplement consist of tablets containing the metal in the form of ferrous ions (Fe2+). Themetal content of these tablets can be determined by dissolving a weighed amount of tablet(s) in dilutesulphuric acid solution and titrating an aliquot of this solution with a standard potassium permanganatesolution as follows: One of the tablets is finely ground and the resulting powder has a mass of 0.4500 g. Distilled water and some sulphuric acid is added until the sample is dissolved. This solution istransferred to a 250.00 mL volumetric flask and made up to the mark. A 25.00 mL portion of this solution is pipetted into a conical flask, and titrated with a 0.0200 M KMnO4solution. The endpoint of the titration is determined when the colourless solution in the conical flask turns abright pink due to the presence of excess permanganate ions. The average titration value is 6.23 mL of the KMnO4 solution. 2KMNO4+8H2SO4+10FeSO4= K2SO4 +2MnSO4 +8H20 +5Fe2(SO4)3 1.Determine the…

Gravimetric Analysis. Please include complete solution, thank you. In the gravimetric determination of sulfate in a 0.2841 g sample of pure Na2SO4, a BaSO4 precipitate weighing 0.4604 g was obtained. The weight of the precipitate was smaller than the theoretical one, since some BaSO4 was converted to BaS during the heating process. Calculate the percent of BaS in the precipitate and percent error of the analysis.
