How would the electron configuration of nitrogen change to make a stable configuration?

lesantik [10]

Answer: The electronic configuration of nitrogen is 1s2 2s2 2p3. Thus nitrogen has a half-filled p orbital, which is comparatively more stable. Thus the p orbital is the outermost orbital. To achieve a stable gas configuration, nitrogen needs to have a fulfilled p orbital.

The pKa of formic acid is 3.75. At pH of 5.00, _______ .

AlladinOne [14]

The pKa of formic acid is 3.75. At pH of 5.00, b) [formate] > [formic acid].

Formic acid is a weak acid. Thus, together with its conjugate base (formate) they form a buffer system. We can calculate the pH of a buffer system using Henderson-Hasselbach's equation.

$pH = pKa + log \frac{[formate]}{[formic\ acid]} \\\\5.00 = 3.75 + log \frac{[formate]}{[formic\ acid]}\\\\\frac{[formate]}{[formic\ acid]} = 17.8$

As expected, at a pH above the pKa, the concentration of formate is higher than that of the formic acid.

The pKa of formic acid is 3.75. At pH of 5.00, b) [formate] > [formic acid].
