Acid-Base Chemistry Concepts

The video tutorial covers the concept of titration, explaining how pH changes during the process. It introduces the dilution equation, M1V1 = M2V2, and adapts it for acid-base reactions as MAVA = MBVB. The tutorial demonstrates how to calculate the molarity of solutions and emphasizes the importance of using coefficients in these calculations. It concludes with a discussion on neutralization reactions, highlighting the role of titration in determining the concentration of acids and bases.
