Welcome to my chemistry lab! 👩🔬
In this video, you’ll learn how to prepare any solution in the chemistry laboratory — step by step, with full concept, calculation, and procedure.
We’ll take M/40 NaOH solution as an example to understand:
🧪 What is molarity and normality
🧮 How to calculate the exact amount of solute to weigh
⚗️ How to prepare a standard solution using a volumetric flask
❓ Why NaOH is a secondary standard solution
🧾 How to apply theoretical knowledge in Lab
Even if you know the theory of molarity, this video will help you finally connect it to real lab practice. Perfect for school, college, and NEET/JEE students, as well as chemistry beginners!
