Bar Keepers Friend is a household cleaner containing oxalic acid, a diprotic acid where pKa1 = 1.27 and pKa2 = 4.27. If the molarity of oxalic acid in one bottle of Bar Keepers Friend is 0.458 M, explain how you would determine the fractional composition of the charge state [H2A] at pH = 3.98? Write out exactly how you would solve the problem (including plugging in the appropriate numerical values to solve the problem without actually calculating the final answer).

You are given a 27 % (w/v) solution of psicose. Molar mass: psicose (C6H12O6) = 180.156 g/mol. You dissolve 6.31 g of potassium formate in 250 mL of 0.25 M formic acid (HCOOH). This solution was then made up to a total volume of 500 mL with distilled water. Potassium formate (KHCO2): molar mass = 84.12 g/mol Calculate the pH of this solution given the pKa of formic acid = 3.77.
Lakes have a natural buffering capacity, especially in regions where limestone gives rise to dissolved calcium carbonate. Write an equation for the effect of a small amount of acid rain containing sulfuric acid if it falls into alake containing carbonate (CO3-2 ) ions.

Although sulphuric acid is a strong electrolyte, an aqueous solution of H2SO4 contains more HSO42- ions, true or false? Justify your answer.
Calculate the pH of a solution containing a salt AcNa derived from a strong base (NaOH) and a weak acid (AcH), like CH3COONa, KF, NaNO2 and so on. In this case two processes have to be considered: 1. Dissociation of the salt, within the assumption that the salt is a strong electrolyte: AcNa → Ac- + Na+, for instance: CH3COONa → CH3COO- + Na+ 2. the hydrolysis of the water Ac- + H2O ⇌ AcH + OH-, for example: CH3COO- + H2O ⇌ CH3COOH + OH- knowing that the initial concentration of the salt is 1.75 M and the acid dissociation constant, Ka , is 2.07e-7. What is the PH?

The first step in purifying the urine collected on the ISS is to treat every liter of urine with 20 mL of 1.0 M H2SO4. To simplify the calculations, lets assume that urine is water. a) What is the pH of a solution of 20. mL of 1.0 M H2SO4 added to 1.00 L water? To determine this, you can safely assume that 100% of the H2SO4 reacts to form H3O+ and HSO4- ions. Use pKa2 (1.92) to determine if any more protons are added to the solution from HSO4-.
You place a beaker containing 1 kg of water in contact with an atmosphere that has a CO 2partial pressure of 10 -2.5 atm and you allow free exchange of gas until equilibrium is established(remember K H =10-1.5 ), then you cap the solution and change the pH by titration. There is nosubsequent exchange of gas with the atmosphere.Please answer the following questions about the solution speciation:a) What is the mass balance equation for dissolved carbonate?
