I'll give you 100%rating if you answer all questions. They are interconnected with each other that's why I can't post them separately Once upon a time, Rasmus and her brother Simone are doing titration to assess the molarity of the sample's total acid content. Using the pH measurements to report acidity, they were ordered to study a clear aqueous solution of an unknown monoprotic acid.They decided to use two methods of experiments to gather essential data for their Chemistry Class.The first method is through a pH strip. To estimate the pH of the sample, Rasmus used a pH strip. Rasmus collected 1 mL of the sample, which came out to have a pH of around 3.3. Furthermore, Rasmus made a new setup in which 1 mL of the same sample was diluted with 9 mL of water, and the pH taken was now around 3.8.The second method is Titration, and Simone used this method. Simone prepared a 10 mL aliquot of the sample and diluted it with 25mL of distilled water. After this, Simone added 2 drops of…
Oxalic acid (H2C2O4) is a diprotic acid with Ka1=5.6×10-1 and Ka2=1.5×10-4. Oxalate ion (C2O42-) also has two base dissociation constants, Kb(1) =6.5×10-11 and Kb2=1.8×10-14. Based on these values, deduce the formula to compute the base dissociation constants of oxalate ion in terms of Kw and Ka1 or Ka2.

What is the [H3O+] of 0.10 M propanoic acid (CH3CH2COOH, can simplify to HPr) (Ka= 1.3x10−5)?Calculate the pH of a 0.050 M solution of ethylamine (C2H5NH2, Kb= 6.4 x10–4).
Determine the pH of 0.01 M solutions of Citric Acid, Sodium Dihydrogen Citrate, Sodium Hydrogen Citrate, and Sodium Citrate solutions. Citric Acid has pKas of 3.13, 4.76, and 6.40. For situations where this cannot be done with ICE/small-x approximation, list the simultaneous equations you could have a computer program solve to arrive at the answer.
Hello, i am provided the pH levels and volumes for Bromocresol Green weak acid by strong base and strong base by weak acid. I am also provided the pH levels and volumes for Phenolphthalein weak acid by strong base and strong base by weak acid. How can we set up a table with all these information to make a graph for each. Heres the data Bromocresol Green: - weak acid by strong base: 12.80 pH; 20.3 mL - strong base by weak acid: 1.49 pH; 20.1 mL Phenolphthalein: - weak acid by strong base: 12.83 pH; 20.1 mL - strong base by weak acid:1.49 pH; 20.1 mL
Your consulting firm wants you to oversee the swimming pool disinfection arm of their business. Your new boss thinks that switching disinfectants from Cl2 gas to bleach (NaOCl) will save cost by eliminating engineering safety controls for Cl2 gas storage. The total acid or conjugate base is added to swimming pools at a concentration of 5*10^-3 M. Assuming activity coefficient = 1, algebraically calculate the pH of the pool where 5*10^-3 M of NaOCl is added. For any simplifications you make, include checks of your assumptions to validate your calculations. Use alpha values, Use Strong-weak acid assumption

Arrange the following 0.1 M solutions in order of increasing pH NaCH3COO, HCl, HCN, NaOH, NH3, NaCN, KNO3, NH4Cl, H2SO3, NaHCO3, Na3PO4 and CH3COOH. (give a brief explanation as to why it is the position, e.g. strong acid/base, larger Ka or Kb etc.) Hint: read through the ‘useful information at the end of the lab’ In the case of the diprotic species (e.g. H2SO3 the major contribution to acidity comes from the first proton loss. The second typically a makes a much smaller contribution) H2SO3: This is a weak acid with Ka1 = 1.7 x 10-2. (This is the dissociation constant associated with the loss of the first proton) CH3COOH: This is a weak acid with Ka = 1.8 x 10-5. HCN: This is a weak acid with Ka = 5.8 x 10-10. Hydrogen carbonate is a weak base with Kb = 2.3 x 10-8. NH3: This is a weak base with Kb = 1.8 x 10-5. Na3PO4: The phosphate ion is a weak base with Kb = 2.2 x 10-2
