The video tutorial covers solving dilution problems using the formula M1V1 = M2V2. It explains how to calculate the concentration of a diluted solution and determine the volume of a solution needed for dilution. Three examples are provided: diluting sodium chloride, preparing a diluted HCL solution, and determining the volume of NaOH required for a specific concentration. The tutorial emphasizes understanding the relationship between initial and final concentrations and volumes.
