Examples of Strong Acid-Strong Base Titration Applications

📚 Quick Study Guide

• 🧪 Strong acid-strong base titrations involve the reaction of a strong acid (e.g., $HCl$, $H_2SO_4$) with a strong base (e.g., $NaOH$, $KOH$).
• 🧮 The equivalence point in such titrations occurs when the moles of acid equal the moles of base. At this point, the $pH$ is typically 7.
• 📊 The general reaction is: $Acid + Base \rightarrow Salt + Water$.
• 💡 Applications include determining the concentration of unknown solutions (standardization) and quality control in various industries.
• ⚗️ The formula used to calculate the concentration is often based on the molarity equation: $M_1V_1 = M_2V_2$, where $M$ is molarity and $V$ is volume.
