Which of the following phrases best describes bicarbonate ions?
A
They are strong oxidizing agents.
B
They are insoluble in water.
C
They act as a weak base in aqueous solutions.
D
They readily form covalent bonds with noble gases.
Verified step by step guidance1
Understand the nature of bicarbonate ions (HCO\_3\^-): they are commonly found in aqueous solutions such as blood and natural waters.
Recall that bicarbonate ions can accept protons (H\^+) in solution, which is characteristic behavior of bases.
Recognize that bicarbonate ions do not act as strong oxidizing agents; their primary role is related to acid-base chemistry rather than redox reactions.
Note that bicarbonate ions are soluble in water, as they exist in equilibrium with carbonic acid and carbonate ions in aqueous environments.
Conclude that the best description is that bicarbonate ions act as a weak base in aqueous solutions because they can accept protons and help maintain pH balance.
