Which of the following is a recommended practice when boiling a solution on a hot plate?

• A. Make Sure That The Glass Ware Being Used Is Heat Resistant.
• B. Inspect The Glass Ware For Cracks Before Putting It In The Hot Plate.
• C. Add Boiling Stones To Facilitate Boiling.
• D. When Removing The Heated Material, Use Polyethylene Gloves To Protect Your Hand From Heat.

Answer: (C)

Adding boiling stones gives the liquid many tiny nucleation sites for bubble formation, which promotes steady, gentle boiling and prevents bumping or sudden splashes. This makes the heating process safer and more controllable on a hot plate. While using heat‑resistant glassware and inspecting for cracks are important safety steps, they don’t directly regulate how smoothly boiling occurs. And when handling hot material, use proper heat‑resistant gloves or tongs rather than polyethylene gloves, which aren’t suitable for protecting hands from heat.
