A sample is known to consists of NaOH, or NaHCO3 or Na2CO3 or possible compatible mixture of these, together with inert matter. With methyl orange, a 1.100 g sample requires 31.4 ml of HCl ( 1.000ml is equivalent to 0.0140 g CaO). With phenolphthalein , the same weight of the sample requires 13.3 ml of the acid. Calculate the percent inert matter in the sample? ( ans. 17.7%)
The chief chemist of the Brite-Metal Electroplating Co. isrequired to certify that the rinse solutions that are discharged from the company’s tin-plating process into the municipal sewer system contain no more than 10 ppm (parts per million) by mass of Sn2+. The chemist devises the following analytical procedure to determine the concentration. At regular intervals, a 100-mL (100-g) sample is withdrawn from the waste stream and acidified to pH = 1.0. A starch solution and 10 mL of 0.10 M potassium iodide are added, and a 25.0-mA current is passed through the solution between platinum electrodes. Iodine appears as a product of electrolysis at the anode when the oxidation of Sn2+ to Sn4+ is practically complete and signals its presence with the deep blue color of a complex formed with starch. What is the maximum duration of electrolysis to the appearance of the blue color that ensures that the concentration of Sn2+does not exceed 10 ppm?
