1) A 0.7502 g sample of impure BaO2(s) was dissolved in acidic solution to produce H2O2 (aq) according to the following reaction given below: BaO:(s) + 2HCI(aq) BaCl2(aq) + H2O2(aq) Then the resulting solution containing H2O2(aq) was titrated against standard KMNO4(aq). In the titration process, the H2O2(aq) was oxidized to O2(g) and the MnO4 was reduced to Mn2+ in acidic medium. The titration required 50.3 mL of 0.025 M KMNO4 solution. What percent of BaO2 was present in the original sample? (BaO2: 169.33 g/mol, Hint: First write and balance the redox reaction).

The concentration of Sn²+ in a solution is determined by titrating it with a 0.1890 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnOq°(aq) + 5Sn²*(aq) + 16H3O*(aq) → 2Mn²+(aq) + 5Sn*(aq) + 24H,O(1) In one experiment, 24.99 mL of the 0.1890-M permanganate solution is required to react completely with 40.00 mL of the Sn2+ solution. Calculate the concentration of the Sn2+ solution. M
A CHM 125 student performed the "Redox Titration" procedure as given in the laboratory manual. In this experiment, the titrant solution of potassium permanganate (KMNO4) was used to determine the percentage of sodium oxalate (NazC2O4) in an unknown sample. The net ionic equation for the titration carried out was: 2MnO4 (aq) + 5C20,7(aq) + 16H*(aq) → 2MN²*(aq) + 10CO2(g) + 8H2O(£) The data provided in the table below was acquired.

A 0.450 g sample of impure CaCO3(s) is dissolved in 50.0 mL of 0.150 M HCl(aq). The equation for the reaction is CaCO3(s) + 2HCl(aq) - CaCl2(aq) + H2O(l) + CO2(g) The excess HCl(aq) is titrated by 5.60 mL of 0.125 M NaOH(aq). Calculate the mass percentage of CaCO3(s) in the sample. mass percentage:
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) +…
Sodium hydrogen carbonate (NAHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: 圖 HCl(aq) + NaHCO,(aq) → NaCl(aq) + H,O(1) + CO,(g) ol. The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 250. mL of a 0.065 M HCl solution. What mass of NaHCO, would she need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.
