"Draw the chemical structure of a molecule of your design that meets all of the following requirements while also being chemically 'reasonable' ('reasonable' based on a general chemistry, Chem 110/112 knowledge of chemical structure and bonding).
The molecule contains nine (9) protons that are ionizable in water and have the following pKa values:
pKa = 13pKa = 10.6pKa = 9.6pKa = 8.0pKa = 5.8pKa = 4.7pKa = 2.4pKa = 1.2pKa = - 0.2
All of these ionizable protons must come only from R-COOH, R-NH3+, or R-OH functional groups, but other substituents (e.g. halogens, etc.) can be used at appropriate locations, as needed.
In addition to drawing the molecule, please briefly explain the rationale behind the chemical structure, including how/why it meets each of the requirements"
Write two balanced half reactions for the titration of iodine with sodium thiosulfate. Indicate what is being oxidized and what is being reduced.
Imagine that you have a 5.50 gas tank and a 4.00 gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
