(a)
Interpretation:
It should be determined whether the carbonate transposition will be effective for detecting SO42- from BaSO4 or not.
Concept introduction:
Carbonate transposition is a reaction which leads to determine that the slightly soluble solids’ aqueous medium anion concentration is sufficient for qualitative analysis.
(b)
Interpretation:
It should be determined whether carbonate transposition will be effective for detecting Cl- from AgCl or not.

- If 1.000ml of a solution of KMnO4 is equivalent to 0.1000mmol of sodium formate (HCO2Na) in the following titration: 2HCO2-+ 2MnO4-+ H2O → 3CO2 + 2MnO2 + 5OH-, what is the value of the KMnO4 in terms of grams of CaO in the volumetric method for calcium in which that element is precipitated as CaC2O4•H2O, the precipitate filtered and dissolved in dilute H2SO4, and the oxalate titrated with permanganate?arrow_forwardA 50-mL solution of 0.5005 N standard NaOH was added to a 0.9250-g sample of Aspirin and was boiled for 10 minutes. After cooling a full pipet of phenolphthalein was added to the solution before it was titrated with 24.7 mL of 0.5015 N standard HCl solution until the disappearance of the pink color. The same procedure was carried using a blank which consumed 4.6 mL of the same standard acid. Calculate for the %Aspirin in the sample. Atom weights: C =12, H =1, O =16.arrow_forwardYou have been given a vinegar solution that is made of water and an unknown concentration (M) of acetic acid. Acetic acid is a monoprotic acid which reacts with NaOH in a 1:1 mole ratio. You have access to a premade NaOH solution of unknown concentration (M), potassium hydrogen phthalate (KHP) and an phenolphthalein indicator as well. Using whatever necessary glassware that would be available to you in the general chemistry lab, design an experiment to determine the Molarity concentration (M), and appropriate statistics, of the acetic acid in the vinegar solution. Write the procedure, including specific glassware, measurements, and calculations in a bulleted or numbered list.arrow_forward
- An acid-base indicator is usually a weak acid with a characteristic color in the protonated and deprotonated forms. In this assignment, you will monitor the color of an acetic acid solution containing Bromocresol Green as an indicator, as the pH is changed and then you will estimate the ionization constant, Ka, for the indicator. 1. Start Virtual ChemLab, select Acid-Base Chemistry, and then select Ionization Constants of Weak Acids from the list of assignments. The lab will open in the Titration laboratory. Bottles of 0.1104 M NaOH and 0.1031 M HAc (acetic acid) will be on the lab bench. The buret will be filled with the NaOH solution and a beaker containing 10.00 mL of the HAc solution will be on the stir plate. The stir plate will be on, Bromocresol Green indicator will have been added to the beaker, and a calibrated pH probe will also be in the beaker so the pH of the solution can be monitored. 2. What is the color and pH of the solution? Yellow, 2.87 3. On the…arrow_forwardFor a titration to be effective, the reaction must be rapid and the yield of the reaction must essentially be 100%. Is Kc > 1, < 1, or ≈ 1 for a titration reaction? Kc is the product of all reaction products (choose from: Multiplied by, added to, divided by, subtracted from) the product of the reactants, with all concentrations of reactants and products raised to their respective stoichiometric powers. As the titration proceeds, the amount of reactants (choose from: Increases, decreases, remains the same) and the amount of products (choose from: Increases, decreases, remains the same). Because the value of the numerator is (Choose from much greater than, much less than, approximately equal to) the value of the denominator, the value of Kc will be (Choose from much greater than, much less than, approximately equal to)1 for an effective titration reaction.arrow_forwardTwo aliquot of a water sample is titrated against a strong acid using phenolphthalein and bromocresol green indicator.

- Copper is regulated in drinking water to protect public health. The relevant reaction is below. The solubility product (equilibrium constant) for the reaction is pK = 19.3. Cu(OH)2 (s) = Cu+2 + 2 OH- The regulatory “action limit” (concentration at which a drinking water utility must take action to reduce levels) is 1.3 mg/L dissolved copper. If the water is at a pH of 7.2, is the level of dissolved copper above, at, or below the action limit? To reduce the concentration of dissolved copper, would you raise or lower the pH? Why?

- One strategy for dealing with the acidification of lakes is to periodically add powdered limestone (CaCO3) to them. In this instance it is assumed that the lake in question has more than enough powdered limestone in it to saturate the water with its ions Ca2+ and CO32- Write the charge balance equation for this system.
