Titrations of Acids and Bases, Part 1

[@MedicalSchoolPrep-i7l]

2 whole semesters of Gen Chem in college and I understood about 10% of all of what I've learned through your whole Gen Chem video series. Titrations, in lab especially, made me want to diiiie. Youre the absolute best. So thankful for you guys! From the bottom of my heart, thank you!!!!!!! 🙏🙏🙏🙏

for the example problem why is the volume of the base 50mL, how do we know to use the volume at the equivalence point?

[@coco.chrisps]

at the EP, the solution is neutralized (the amount of added titrant neutralized the unknown sol'n). If it took 50 mL of 1 M NaOH to neutralize the reaction, then that must be proportional to the amount of the unknown volume and concentration of the analyte (that's why we use (na)[A](Va)=(nb)[B](Vb); this equation tells us that the amount needed to neutralize a reaction).
