When aqueous FeCL3 is combined with 100.00 mL of a base solution containing Ba(OH)2, 0.567g of rust-red solid is precipitated. Assuming that barium hydroxide was completely consumed through this reaction, what was the molar concentration of the original Ba(OH)2 solution.
2) ) A student who wants to make the determination of calcium, and he dissolved impure 0.1453 g CaCO3 solid by pretreatment, then precipitated calcium ions by adding ammonium oxalate. He then titrated the released oxalate ions with the adjusted 0.01923 M KMNO4 solution, spending 15 mL of KMNO4 for titration. In this case, find the mass percentage of calcium in the sample. (Ca: 40 g/mol; CaCO3:100 g/mol) 5C,0,2- (aq) + 2MNO4 (aq) + 16H* (aq) > 10CO2 (g) + 2MN2* (aq) + 8H20(aq)
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?

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: %

The amount of protein in a sample of cheese was determined by a Kjeldahl analysis. After digesting a 0.9814-g sample of cheese, the nitrogen is oxidized to NH4+, converted to NH3 with NaOH, and distilled into a collection flask containing 50.00 mL of 0.1047 M HCI. The excess HCI is then back titrated with 0.1183 M NaOH, requiring 22.84 mL to reach the bromothymol blue end point. Report the %w/w protein in the cheese.
