< Question 1 of 15 > EDTA is a hexaprotic system with the pK, values: pKu1 = 0.00, PK 2 = 1.50, PK 3 = 2.00, pK24 = 2.69, pK5 = 6.13, and pK6 = 10.37. The distribution of the various protonated forms of EDTA will therefore vary with pH. For equilibrium calculations involving metal complexes with EDTA, it is convenient to calculate the fraction of EDTA that is in the completely unprotonated form, Yº-. This fraction is designated ayt....
EDTA is a hexaprotic system with the pKa values: pKa1=0.00, pKa2=1.50, pKa3=2.00, pKa4=2.69, pKa5=6.13, and pKa6=10.37. The distribution of the various protonated forms of EDTA will therefore vary with pH. For equilibrium calculations involving metal complexes with EDTA, it is convenient to calculate the fraction of EDTA that is in the completely unprotonated form, Y4−. This fraction is designated αY4−. Calculate αY4− at two pH values; ph=3.20 and ph=10.20

1. (8 pts) Virtually every pchem textbook has a table of enthalpy values for 25°C. One use for these may be to calculate the enthalpy for a phase change such as compounds boil at 25°C. You are going to calculate the percent difference between the heat of vaporization of ethanol using data for 25°C and that at its boiling point of 78°C. boiling. However, not too many a) Write the chemical equation that shows the vaporization of 1 mol of...

Find the best reducing agent from Cu+, Ag+ F2 and Fe3+ #1. In the reduction table i can see several repeated values of Fe3+ one is equal to 0.77v and the second one is equal to -0.036v so, which one do I choose? Please explain. #2.If I'm asked to find the best oxidation agent, from the values already provided (Cu+, Ag+ F2 and Fe3+) which one would it be? and how would I decide from repeated values, like in #1,...
1. How do I read the half reaction table? 2. If im asked for the best reducing agent from Cu+, Ag+, F2, and Fe3+, where do I look first in the table? before the arrow or after the arrow? 3. Sometimes a value that has originally a positive (V) from the table it will have the negative sign in a homework problem, and viceversa, so the question is, how do I use the positive and negative signs in respect to...
