• A. 66.6% w/v
• B. 66.8% v/v
• C. 66.7% w/w
• D. 67.0% w/w

Hint:

IP = 66.7% w/w (Weight). USP = 85% w/v (Volume). Don't mix them up!

Answer 1

The Correct Option is C

Step 1: Concept
Syrups are concentrated aqueous preparations of a sugar or sugar substitute with or without medicinal substances.

Step 2: Meaning
Different pharmacopoeias specify different concentrations; USP uses weight/volume (w/v), whereas IP uses weight/weight (w/w).

Step 3: Analysis
According to the Indian Pharmacopoeia, Simple Syrup is prepared by dissolving 66.7 grams of sucrose in enough purified water to produce 100 grams of syrup.

Step 4: Conclusion
This results in a final concentration of 66.7% w/w.

Final Answer: (C)
