What is the pH of a 1.5 M solution of trifluoroacetic acid (CF3CO2H) with pKa = 0.2? What will the pH be if 0.0100 mol HA (pKa = 2.00) and 0.0100 mol A- are mixed together to make a 1.00 L solution? What is the pH of a 0.500 M solution of ...

What is nylon-6,10 and what is it used for? What is the pKa1 of H2C2O4? _ Ka1 = 6.5x10-2. What is spectroscopy? Which is larger? K^+ or Ar ? What is DPPF ? What is Mylar? What is supercooling? What is a pion? What is a centrifuge? What is it used for?
pKa is the measurement of acidity or basicity of achemicalorfunctional group. The acidity or basicity of a chemical or functional group can be defined in two ways: The ability to accept or donate a proton. The ability to accept or donate a lone pair of electrons. ...
c) water will work as good as either acid d) both are equally effective The answer isa) acid A. I understand that when pKa is higher than pH, deprotonation occurs. Which makes choice a) the correct answer... I just feel like I'm missing something. I guess I'm not sure how adding...

Produces the greatest degree of vasodilation of all currently used local anesthetics. pKa. 8.9.a pH of plain solution. 5.0 to 6.5. pH of vasoconstrictor-containing solution. 3.5 to 5.5. Onset of action. 6 to 10 minutes. Effective dental concentration. 2% to 4%. Anesthetic half-life. 6...
The pKa of [HDABCO]+ (the protonated derivative) is 8.8, which is almost the same as ordinary alkylamines. The nucleophilicity of the amine is high because the amine centers are unhindered. It is sufficiently basic to promote C–C coupling of terminal acetylenes, for example, phenylacetylene...
