Select the statement that best describes a buffer.
a. A buffer causes acidic solutions to become alkaline, and alkaline solutions to become acidic.
b. A buffer stabilizes the pH of a solution by preventing acids or bases from dissociating.
c. A buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.
d. A buffer prevents the pH of a solution from changing when an acid or base is added.
e. Buffered solutions are always neutral, with a pH of 7.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
