A.2. Table of Electrode Potentials In Table A.1, you should have a value for Eed or Exid for each of the electrode systems you have studied. Remembering that for any electrode system, Ed=-Exid, you can find the value for Ed for each system. List those potentials in the left column of the table below, in order of decreasing (more negative) value. EO reduction (Eº Ag+,Ag = 0.00 V) Electrode reaction in reduction (Eº E reduction H.H₂ = 0.00 V) The electrode potentials you have determined are based on setting E = 0.00 V. The usual convention in Agt.Ag electrochemistry is to set EH¹,H₂ = 0.00 volts, under which conditions E "Ag, Ag red = +0.80 V. Convert from one base to the other by adding 0.80 volts to each of the electrode potentials in the first column, and enter these values in the third column of the table. Why are the values of Ed on the two bases related to each other in such a simple way?

0.1890 grams of an unknown organic acid containing 2 carboxylic groups was dissolved in about 50 mL of water in a 250 mL Erlenmeyer flask and titrated against 0.1000 M NaOH solution using bromothymol blue indicator. 34.62 mL of titrant was used to achieve end point. Calculate the molar mass of the unknown. Write answer with two decimal places only. No units please.

2.2 6. (1) Define pH in words. The strong acid HClag has a pH value of 1, use the following equation for a strong acid: Claa HClaa Hog + and convert the following expression to deduce the hydrogen ion concentration: pH = -log10 [H+] (ii) Use the above expression to deduce the pH of HCl (ag) given the concentration of the acid to be 4.5 mol/dm³ pH =

Hello, I hope you are doing well on this fine day. For the following quetion please read carefully the question and instruction. PLEASE ANSWER QUESTION IN 20 MINTUES NOT MORE PLEASE AND THANK YOU. If you do answer the question correctly and post it in the next 15 minutes, NO NEED TO SHOW THE WORK, I JUST WOULD LIKE THE CORRECT ANSWER AS SOON AS POSSIBLE. I will write a wonderful and generous feedback/review/rating about you.  2.077 g of salicylic acid is used in the reaction to synthesize ethyl salicylate, what is the minimum amount of ethanol in mL necessary to convert all of the salicylic acid to ethyl salicylate? The molecular weight of salicylic acid is 138.12 g/mol, the molecular weight of ethyl salicylate is 166.176  g/mol. The molecular weight of ethanol is 46.069 g/mol and its density is 0.789 g/mL.
