And its conjugate - Study guides, Class notes & Summaries

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...
