This video, titled "Pharma QC Dilution Doubts," is a tutorial for freshers in pharmaceutical Quality Control (QC) that explains various types of dilutions and their interconversions.
​Here is a summary of the main topics covered:
​Percentage Dilution [00:27]
​Discusses the three types: Weight by Volume, Volume by Volume, and Weight by Weight.
​Provides a step-by-step example for preparing a 0.05% solution.
​Parts Per Million (PPM) Dilutions [01:46]
​Explains the relationship between mg and PPM (1 mg = 1000 PPM).
​Demonstrates how to calculate PPM and how to create a target PPM dilution, including methods for using multiple steps for very low PPM concentrations.
​Relationship Between PPM and Percentage [04:21]
​Outlines the conversion factor: 1% is equivalent to 10,000 PPM.
​Molar Dilutions [05:25]
​Explains that a 1 Molar solution is prepared by dissolving the substance's molecular weight in 1000 ml of solvent.
​Provides a formula and examples for calculating the required weight for a target molarity.
​Molar Solutions of Concentrated Liquids (e.g., Acids) [06:57]
​Introduces a formula using density, molecular weight, and purity to calculate the required volume (in ml) of a concentrated liquid (like HCl or Orthophosphoric Acid) to prepare a 1 Molar solution.
​Equivalent Weight / Conversion Factor [09:13]
​Details how to calculate the weight of a compound required to be equivalent to a specific weight of an element within it (e.g., how much Calcium Carbonate equals 1 gram of Calcium).
​Equivalent Weight in Pharmaceutical Products [11:00]
​Provides formulas for calculating the equivalent weight of the active ingredient from different product forms:
​Tablets or Capsules [11:00]
​Liquids/Syrups [11:36]
​Creams or Ointments [12:25]
