Question

The spatulation process is well suited for mixing of which of the following powder?

• A. Hygroscopic
• B. Volatile
• C. Eutectic
• D. Effervescent

Answer 1

The Correct Option is C

Step 1: Understanding the spatulation process. - Spatulation is a gentle mixing technique using a spatula on a smooth surface. - It is used for mixing powders that are prone to liquefaction upon contact. 

Step 2: Explanation of incorrect options. - (A) Hygroscopic: These absorb moisture and require special handling. - (B) Volatile: Best handled in closed containers, not with spatulation. - (D) Effervescent: Reacts with moisture; requires minimal handling to prevent premature reaction. 

Step 3: Selecting the correct option. Since eutectic mixtures tend to liquefy upon contact, the correct answer is (C) Eutectic.
