The quantity of antimony in a sample can be determined by an oxidation–reduction titration with an oxidizing agent. A 6.19 g6.19 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb3+⁢(aq). The Sb3+⁢(aq) is completely oxidized by 30.5 mL of a 0.115 M aqueous solution of KBrO3⁢(aq). The unbalanced equation for the reaction is BrO^− 3(aq) + Sb^3+(aq)⟶Br^−(aq)+Sb^5+(aq)(unbalanced) Calculate the amount of antimony in the sample and its percentage in the ore. mass of antimony in grams: percentage of antimony:
The concentration of hydrogen peroxide in a solution is determined by titrating it with a 0.1217 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnO4 (aq) + 5H₂O₂ (aq) + 6H3O+ (aq) → 2Mn²+ (aq) +50₂ (1) + 14H₂O(1) In one experiment, 19.09 mL of the 0.1217 M permanganate solution is required to react completely with 40.00 mL of the hydrogen peroxide solution. Calculate the concentration of the hydrogen peroxide solution. Concentration = M
The iron content of iron ore can be determined by titration with K₂Cr₂O₇ according to the equation 14H⁺(aq) + Cr₂O₇²⁻(aq) + 6Fe²⁺(aq) → 6Fe³⁺(aq) + 2Cr³⁺(aq) + 7H₂O(l) Diphenyl amine is used as an indicator as it changes color from green to purple when the endpoint is reached. A sample of iron ore with a mass of 3.255 g was dissolved with HCl and then treated with a reducing agent to convert any Fe³⁺ in the ore to Fe²⁺. Titration with 0.0645 M K₂Cr₂O₇ solution required 45.65 mL of the solution to reach the endpoint. The molar mass of Fe is 55.85 g/mol. Calculate the mass percent iron in the ore.
The discharge of chromate ions (CrO42) to sewers or natural waters is of concern because of both its ecological impacts and effects on human health if the receiving water is used as a drinking water source. One way in which chromate can be removed from solution is by its reaction with ferrous iron (Fe²+) to form a mixture of chromic hydroxide and ferric hydroxide solids [Cr(OH)3(s) and Fe(OH)3(s), respectively], which can then be filtered out of the water. The overall reaction can be represented as CrO4 + 3Fe²+ + 8H₂O → Cr(OH)3(s) + Fe(OH)3(s) + 4H+ How much particulate matter would be generated daily by this process at a facility that treats 60 m³/h of a waste stream containing 40 µg/L CrO4²- if the treatment reduced the Cr concentration enough to meet a discharge limit of 10 µg/L (MCL proposed in 2013, voted into law in 2015 and ruled invalid in 2017 for California) or 50 µg/L (current MCL) CrO4²-?

Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide: 2 MACO,(s)+0,(9) -→2 MuO,(s)+2 CO,(9) In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide: 3 MnO,(s)+4 Al(s)-3 Mn(s)+2 Al,O3(s) Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced.
One method for chemical analysis involves finding a reactant that will precipitate the species of interest, but not the other species. The mass of the precipitate is then used to determine the mass of the species of interest present in the original sample. For example, calcium ions can be precipitated from an aqueous solution by adding of sodium oxalate Na2C2O4. The balanced equation is: Ca2+(aq) + Na2C2O4 (aq) --> CaC2O4 (s) + 2 Na+ (aq) Suppose you had a solution with approximately 15.0 g of calcium ions. Show by calculation whether the addition of 15.0 g of sodium oxalate will precipitate all of the calcium ions present in the sample.
