Flashcards

What is an Acid?

A substance that donates a proton (H⁺).

Base Division Exclusion

It is NOT a volatile base. Bases are substances that accept protons.

Acid-Base Buffers

Substances that minimize pH changes by neutralizing added acids or bases in a solution.

Heparin's Impact on Acid-Base

True. Excess heparin can alter pH, bicarbonate (HCO3), carbon dioxide (CO2), and base excess (EB).
