The Kₐ of carbonic acid is 4.3 x10⁻⁷ . H₂CO₃ ⇄ H⁺ + HCO₃ ⁻ This means that H₂CO₃ is a A) Good hydrogen-ion acceptor.
B) Poor hydrogen-ion acceptor.
C) Good hydrogen-ion donor.
D) Poor hydrogen-ion donor.

A good hydrogen ion acceptor

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
