CH_4E_SC_EXP-9- VARIATION DU pH AU COURS D’UNE RÉACTION | DOSAGE pH : LE PIÈGE ÉVITÉ

🧪 *Struggling with pH curves?* Equivalence point, pH jump, pKa, half-equivalence point, buffer solutions, choosing the right indicator… We'll tell you EVERYTHING you need to know 📈 #chemistry #pHmetry #acidbasetitration #pKa #examrevision In this video, we'll review the chemistry curriculum point by point on *acid-base titration by pH measurement* – using real course material (strong acid/strong base, weak acid/strong base, weak base/strong acid). 🔹 *On the agenda:* ⏱️ TIMESTAMPS (click to access the chapter) 00:00 - INTRODUCTION 00:49 - 📊 ANALYSIS, TITRATION, AND pH 01:54 - 🔬 Part 1: THE ACID-BASE PUZZLE – At the heart of the laboratory 02:44 - 📈 Part 2: DECODING CURVES – Reading pH 03:28 - 🎯 Part 3: FINDING EQUIVALENCE – Graphical methods 05:18 - 🎨 Part 4: COLORED INDICATORS – Assessing equivalence 05:56 - 🛡️ Part 5: THE POWER OF BUFFERERS – Chemical resistance 06:42 - 🌍 Part 6: CONTROLLING ACTUAL pH – Practical applications 07:39 - ❓ CONCLUSION & QUESTION – Does acid-base equivalence govern our lives? 🎯 *What you'll be able to do after this video:* ✅ Plot and interpret a pH = f(V) curve ✅ Determine an unknown concentration (CA or CB) ✅ Find the pKa of a conjugate acid-base pair ✅ Explain why a solution is buffered ✅ Choose the appropriate indicator (BBT, phenolphthalein, methyl orange, etc.) ===== 👉 *Subscribe* so you don't miss any chemistry review sessions 🔔 ===== *And you, which type of titration did you find most difficult: strong acid – strong base, weak acid – strong base, or weak base – strong acid?* Tell me in the comments, and I can give you practice exercises with explanations for the one you're struggling with! 💬 👏 Thank you for watching this video. Keep your pH... always in the turning zone for success. See you soon! 📚 *Based on a complete lesson* (9- pH VARIATION DURING A REACTION BETWEEN AN ACID AND A BASE). ===== Link to Playlist Chemistry 4th Experimental Sciences:    • CHIMIE - 4E - SCIENCES _ EXP   ===== Hashtags #buffersolution #equivalence #chemistry #acidweak #strongbase #colorfulindicator #ph #lotfiprophy #classcourse #easychemistry ===== اشترك في القناة وفعّل جرس الإشعارات 🔔 حتى لا يفوتك أي درس جديد! اضغط على الرابط:    • فيزياء - السنة السابعة
