Please answer the following question: Suggest a strategy using selective precipitation (which salts containing precipitating ion would you add and in what order) to purify wastewater contaminated with Ag+, Ba2+, Fe3+ and Na+. The purified water should only contain Na+ which is safe to drink.
A shipment of containing NaOH (40 g/mol) and Na2CO3 (106 g/mol) was declared to contain less than 10 % impurity. However, Noel is suspicious that the declared impurity is higher. Being the best and brightest employee of the year, Noel weighed 1.000 g sample, dissolved in 50.0 mL of distilled water and titrated with cold 0.5000 M HCl. With Phenolphthalein as indicator, the solution turns colorless after the addition of 30.00 mL of the acid. Methyl Orange is then added, and 5.00 mL more of the acid is required before this this indicator changes color. Calculate the following: a.

While working in a metal processing facility, Letlen had accidentally mixed two metal vatstogether creating an alloy. One vat was labeled for cadmium, while the other was not. It canbe assumed that these are of pure metal composition. To identify this metal, Letlen took 1.000 g of the homogenous alloy sample composed ofcadmium and the unknown metal, dissolved, and diluted it to exactly 100.0 mL in avolumetric flask. A 20.00-mL aliquot was taken and titrated this using 22.82 mL of 0.05000M EDTA. In a second 20.00-mL aliquot, the Cd was masked through the addition of HCN/NaCN buffer.The titration of the unknown metal in the aliquot required 15.13 mL of EDTA.MW: Cd (112.411 g/mol) a. Calculate the moles of Cd and the moles of unknown metal in the 20.00-mL aliquot.b. Calculate the moles of Cd and the moles of unknown metal in the sample.
