Accepted Answer

Simple distillation is effective with a difference of at least 25°C; use fractional distillation for smaller differences.

Answer

Simple distillation is effective with a difference of 5°C; use fractional distillation for larger differences.

Answer

Simple distillation is effective with a difference of at least 10°C; use fractional distillation for larger differences.
