G The aminium salt of an amine (e. g., R-NH3+) has a pKa of 9.8, and a small amount of this salt is added to a solution that is buffered at pH 11. If the pH changes to 10.6, then what fraction of the compound will be in the unprotonated, amine (amino) form? Enter your answer as a percent to the nearest ones.

100 points answer quick the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

You encounter a solution that is acidic and you decide to test it by adding a small amount of a strong acid. the ph lowers slightly but is approximately unchanged, and still remains acidic. what can you say about the solution? a. it is a buffer solution. b. it is not a buffer solution it is a strong acid solution. d. the solution has been neutralized. e. the solution has excess acid present
