Write a complete balanced redox reaction, wherein electron(s) are transferred between Coenzyme Q and lipoic/dihydrolipoic acid,
1 answer:
Answer:
attached below
Explanation:
Attached below is the complete balanced redox reaction
Oxidation as seen in the first Redox equation is the addition of hydrogen or the loss of electrons
For The first reaction
The reactant = lipoic acid
product = dihydrolipoic acid
second reaction
The reactant ; ubiquinone
product ; ubiquinol

Answer
a) A solution with a hydronium molarity of 0.00045 is acidic. True
Doing the calculus of pH
b) pH is a way to express the hydronium concentration over a wide range. True
pH means –Log[H+] and this value is used to express a wide range of hydronium concentration sometimes obtaining pH minor than zero.
c) Percent K and Fe are determined by doing ion exchange then a pH titration. False
Usually, Fe is determined by redox titration with potassium permanganate due to it’s more accurate. On the other hand, K is determined usually by volumetric process which includes precipitation like potassium picrate precipitate
d) About 0.2M HCl is the reagent used for the pH titrations. False.
In order to do pH titration, it is possible to use a wide range of HCl concentrations and other acids as reagent if the analyte is a basic compound. Otherwise, if the analyte is an acid compound you should use a basic compound as reagent.
e) A Lewis base is specie that can donate a proton to an acid. False
A Lewis base is an electron pair donor.
