مبحث تیتراسیون اسید و باز ضعیف
Understand the Problem
السؤال يسأل عن موضوع تيتراسیون (أو معايرة) الأحماض والقواعد الضعيفة، وهذا يتضمن فهم كيفية القيام بتجارب الكيمياء التي تشمل تفاعلات الأحماض والقواعد وكيفية تحديد النقاط المناسبة للتغيير في التركيز.
Answer
Titration involves determining an unknown concentration using a known concentration of acid or base.
In an acid-base titration, a known concentration of a base or acid is used to determine the unknown concentration of the other. Weak acids form conjugate bases, while weak bases form conjugate acids. The pH varies depending on the strengths of the reactants.

More Information
Titration is a fundamental technique in analytical chemistry, often employed to find the concentration of an unknown solution. The pH can indicate the completion of a titration. In cases of weak acids or bases, the conjugate's strength plays a crucial role in determining pH outcomes.
Tips
Confusing the direction of pH change based on weak or strong acids and bases is common. Remember that a strong conjugate corresponds to a weak counterpart.
