Back Titrations Question 1 A 10.0 g piece of rusty steel wool is dissolved in 200.00 ml of 1.00 M sulfuric acid. The excess sulfuric acid is determined by titration with a 0.500 M sodium hydroxide solution. 300.00 mL of sodium hydroxide is required to neutralise the acid. What was the % purity of iron in steel wool? Question 2 A 3.145 g sample of a certain lead ore containing lead(II) carbonate‚ PbCO3‚ was heated gently with 25.00 mL of nitric acid of concentration

Determination of KC of Iron(III) Thiocyanato by Spectometry Theory: This study uses the method of measuring the equilibrium constant‚ Kc‚ for solution made of different initial reactant concentrations to determine the Kc for the reaction of iron(III)) and thiocyanato. The formula: Fe3+ +SCN- ⇔ FeSCN2+ The concentrations of the three substances at equilibrium will be determined by the stoichiometry of the reaction and the stoichiometric determination of the concentration of the complex AB.

a thermometer to measure the temperature of the solution obtained in the conical flask. Fill 29.00mL of HCL in the burette. Use a pipette to transfer 10.00mL portion of the solution into a conical flask and drop 5 drops of methyl orange into it by using a dropper. Then‚ slowly open the mouth of the burette and allow HCL to flow into the conical flask containing Ca (OH)₂ and methyl orange as the indicator. Titrate the solution until the yellow colour of the solution turns into orange. Repeat the experiment

An investigation into the total acid content of assorted brands of lemon and lime soft drink Abstract: The aim of this experiment was to determine the total levels of carbonic acid concentration in 3 differing brands of lemon and lime soft drinks. Research Question: Does the acid content in three different lemon and lime flavoured soft drink brand differ significantly? The purpose of this investigation is to calculate the total acid content within different brands of lemon

Procedure: Part I: Titration with an Indicator 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Add two drops of the indicator‚ phenolphthalein‚ to the acid in the flask. 7. Using the slider on the right hand side‚ add NaOH to the HCl in the Erlenmeyer

solution* Balanced equation for hydrochloric acid and calcium hydroxide: Ca(OH)2 + 2HCl → CaCl2 + 2H2O Qualitative Data: The dark pink color the indicator gave it immediately vanished after a specific amount of Hydrochloric Acid was added by titration into the solution of Calcium Hydroxide. Due to this being an exothermic reaction‚ it has been assumed that the temperature of the reaction had increased. DCP2: Averages for the ∆volume: (VfVi) Given: See chart above. Unknown: Average the Volume

Vinegar Titration Lab Procedure: 1.) Obtain ~100 mL of NaOH. Record the molarity on the data table. 2.) Set up a ring stand with a buret. 3.) Place 5mL of vinegar in a 125 mL Erlenmeyer flask. Dilute the vinegar with 25 mL of water and add two drops of phenolphthalein. 4.) Fill the buret with NaOH. Record the initial volume of the buret in your data table. 5.) Titrate the vinegar sample until the first faint pink color does not disappear. 6.) Record the final volume of the buret in your data
