ab experiment by adding drops of KMno4 to a solution of distilled water and Iron (II) ammonium sulfate. I measured the iron ammonium sulfate in grams and added the same amounts into two flasks. I then added 25mL of distilled water and mixed. Then I added 5 mL of H2SO4 (sulfuric acid) into the solution. After that, I slowly added drops of KMno4 until the solution turned a pink color (reached end point). I measured the initial and final volume of KMno4. What would be the balanced equation for this reaction? How can I find the moles of KMno4 solution needed to react with all of the 0.100M FeSO4 solution? How do I calculate the molarity of KMno4?
An EDTA solution was prepared by dissolving the disodium salt in 1 L of water. It was standardized using 0.5063 gram of primary standard calcium carbonate (MM: 100.08) and consumed 28.50 mL of the solution. The standard solution was used to determine the hardness of a 2 L sample of mineral water, which required 35.57 mL of EDTA solution. 1. What is the analyte in the analysis? Answer 2. What is concentration (M) of the EDTA solution used in the analysis? Answer 3. What is the concentration (ppm) of CaCO3 in the sample?

CALCIUM PEROXIDE OCTAHYDRATE (CaO2.8H2O) SYNTHESIS CaCO3 + 2 HCl --> CaCl2 + CO2 + H2OCaCl2 + 2 NH3 + H2O2 + 8 H2O --> CaO2.8H2O + 2 NH4+ + Cl- Question: Calculate the percentage yield of the product you have obtained.(just find the theoritical value) procedure: 5 g of pure CaCO3 is added in small portions to 10 mL of water and 20 mL of 18% HCl in a 100 mL beaker and mixed with a bottle. During this process, the mixture should be boiled in order to remove the CO2 formed. When the CaCO3 addition is complete, it is observed that a sufficient amount of precipitate is formed at the bottom of the container. The solution is filtered while hot, the excess water is evaporated and cooled with ice water. Thereupon, he says 25-30 mL of 6% H2O2 solution, 5 mL. NH3 and 100 mL water are gradually added with stirring. After stirring for a while, the crystals formed are filtered, washed several times with water and dried in a desiccator.!(Work in a 1: 4 ratio.)!
EXERCISE 1: Preparation of a standard solution of copper(II) sulfate pentahydrate 1. Weigh out accurately 9.99 g of copper(II) sulfate pentahydrate (CuSO4·5H2O) by taring using a clean and dry empty 250-ml beaker. 2. Add tap water to the beaker to reach the 50-mL mark on the side of the beaker. 3. Dissolve all the crystals of CuSO4·5H2O in the water using a clean glass rod for stirring. 4. Then using a glass funnel transfer all the blue solution to a 100-mL volumetric flask. Rinse the beaker with about 10 mL of water and transfer the solution to the volumetric flask. Repeat the rinsing of the beaker with another 10 mL of water and transfer the solution to the volumetric flask. This is called quantitative transfer of the solution. 5. Then add enough water to reach the calibration mark of the volumetric flask. (You will need to use a dropper to add the last few drops of water to ensure the meniscus is on the calibration mark). Close the volumetric flask with a stopper and mix the…
