The tip of funnel should touch the wall of the breaker in order to avoid____________________?
Correct answer: B. splashing
- A. Inconsistent flow of filtration
- B. splashing
- C. premature crystallization
- D. all of above
Explanation
Allowing the funnel tip to touch the beaker wall lets the liquid run smoothly down the wall instead of falling freely, thereby preventing splashing. Students may choose all of the above because the other effects can occur during poor filtration, but the direct purpose described here is avoiding splashing.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
