Answer:

Element Lithium

Explanation:

The element with the highest second ionization energy is lithium. It belongs to the alkaline metal group I.e group one metals

It has the highest second ionization energy because it is very difficult to remove the electron from the 1s orbital.

Its atomic number is 3. The electronic configuration is 1s2 2S1

An acid with a p K a of 8.0 is present in a solution with a pH of 6.0. What is the ratio of the protonated to the deprotonated f

olga2289 [7]

Explanation:

According to the Henderson-Hasselbalch equation,

pH = $pK_{a}$ + $\frac{log[A^{-}]}{[HA]}$

Given values are pH = 6, $pK_{a}$ = 8

Putting given values into the above equation as follows.

6 = 8 + $\frac{log [A^{-}]}{[HA]}$

$\frac{log[A^{-}]}{[HA]}$ = -2

$\frac{[A^{-}]}{[HA]}$ = antilog -2

= 0.01

But according to the question, we need protonated to deprotonated ratio of $\frac{[HA]}{[A^{-}]}$

$\frac{[HA]}{[A^{-}]}$ = $\frac{1}{0.01}$

$\frac{[HA]}{[A^{-}]}$ = 100

Thus, we can conclude that ratio of the protonated to the deprotonated form of the acid is $\frac{100}{1}$ .
