The steps for determining the concentration of a sample of hydrochloric acid are listed below :Step (1): A 0.1038 M standard sodium carbonate solution was prepared by dissolving 2.750 g ofanhydrous sodium carbonate solid in deionised water and made up to 250.0 cm3.Step (2): 25.0 cm' of the standard solution obtained in Step (1) was transferred to a clean conical flask andthen a few drops of methyl orange were added.Step (3): The sample of hydrochloric acid was put into a burette. The standard solution in the conicalflask was titrated with the hydrochloric acid.Step (2) and Step (3) were repeated for several times.

The presence of soluble chromium compounds in wastewater is of great environmental concern. As part of an investigation to remove the metal, a laboratory technician adds 150.00 mL of 1.75 M Cr(NO3)3 to 70.00 mL of 1.41 M K2S, resulting in a precipitate of Cr2S3. The concentrations of Cr3+ in solution after the reaction is completed is:
A sample consisting of Na2CO3 and NaHCO3, and inert matter weighs 6.7447 grams. It is titrated with 0.16 N HCI with phenolphthalein as the indicator, and the solution became colorless after the addition of 22.65 mL. Another duplicate sample was titrated with HCI using methyl orange as indicator. It required 56.94 mL of the acid for the color change. What is the percentage of NaHCO3 (84g/mole) in the sample? (Answers should be written in 2 decimals place and do not include the UNIT)
The U.S. standard for arsenate in drinking water requires thatpublic water supplies must contain no greater than 10 partsper billion (ppb) arsenic.

A 50.0 ml solution contains only Na2SO4 (MW 142.04 g/mole). If 40.0 ml of 0.25 M BaCl2 is needed to precipitate all the SO42- as BaSO4, what mass of Na2SO4 was in the original solution? What is the concentration of Cl- in the final solution?
Tungsten trioxide (WO,) has a rich yellow color and is often used as a pigment in ceramics and paints. To test a ceramic vase for its WO, content, a 10.15 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO, to W³+. The resulting W3+ was transferred to 500.0 mL of 1.00 M HCI. A 100.00 mL aliquot of the HCl solution required 14.78 mL of 0.08271 M potassium permanganate (KMNO,) to reach the purple endpoint. A blank required 0.26 mL. Balance the redox reaction. redox reaction: MnO, + W3+ Mn2+ + WO3+ Determine the percent WO, in the ceramic sample. percent WO3: %

Hydrogen peroxide solutions can easily be decomposed by dust, trace amounts of metals or light. It is therefore necessary to periodically determine the purity of the peroxide solutions. This can be done via a redox titration as follows: • The density of a particular surgical grade hydrogen peroxide solution is 1.1lg.cm. • Exactly 10 ml of this solution was pipetted and quantitatively transferred, along with a sufficient amount of a dilute sulphuric acid solution, into a 250.00 mL volumetric flask and made up to the mark. • A 25.00 ml portion of this diluted solution is pipetted into a conical flask, and titrated with a 0.372 M KMNO, solution. The endpoint of the titration is determined when the colourless solution in the conical flask turns a persistent bright pink due to the presence of excess permanganate ions. • The average titration value is 26.20 ml of the KMNO, solution. The reaction stoichiometry is as follows: 2KMN0, (aq) + 3H, so,(aq) + 5H,0, (aq) 2MnSo, (aq) + K2So, (aq) +…
