Acid-base theories are fundamental to understanding chemical reactions in biological systems. From Arrhenius to Lewis, these concepts explain how substances interact, donate or accept protons, and form bonds in aqueous solutions.
pH and calculations quantify acidity and basicity, crucial for maintaining balance in living organisms. These measurements, along with Ka values and water autoionization, help us grasp the delicate equilibria that sustain life processes.

defines acids as substances releasing H+ ions in water, bases release OH- ions (hydrochloric acid, sodium hydroxide)
Brønsted-Lowry theory broadens definition: acids donate protons, bases accept protons, forming conjugate acid-base pairs (ammonia accepting H+ from water)
further expands concept: acids accept electron pairs, bases donate electron pairs, forming coordinate covalent bonds (boron trifluoride accepting electrons from ammonia)
pH and pOH calculations
pH measures acidity: negative log of H3O+ concentration pH=−log[H3O+] (lemon juice pH ~2)
