Which of the following materials is considered the most polar in normal phase chromatography? A) Silica (SiO2) B) Titania (TiO2) C) Zirconia (ZrO2) D) Alumina (Al2O3)
Understand the Problem
The question is asking which material is the most polar when used in normal phase chromatography. This implies the need for knowledge about the polarity of the given materials, which is a chemistry-related topic.
Answer
Silica (SiO2) is considered the most polar in normal phase chromatography.
The material considered the most polar in normal phase chromatography is Silica (SiO2).
Answer for screen readers
The material considered the most polar in normal phase chromatography is Silica (SiO2).
More Information
Silica gel is widely used as a stationary phase in normal phase chromatography due to its high polarity. It provides strong interactions with polar analytes, facilitating their separation.
Tips
Confusion can arise when considering the role of stationary and mobile phases; remember the stationary phase (silica, in this case) is where polar interactions are key.
