In paper chromatography, which one of the following acts as the stationary phase?a.Aluminab.Silica gelc.Narrow glassd.Cellulose

Break Down the Problem

1. Identify the components in paper chromatography.
2. Determine what stationary phase means in chromatography.
3. Analyze the options provided.

Relevant Concepts

• Stationary phase: In chromatography, the stationary phase is the phase that does not move. It helps to separate components of a mixture based on their interactions with the stationary phase.
• Paper chromatography: Typically uses a thin layer of cellulose (the material of the paper) as the stationary phase.

Analysis and Detail

1. Alumina (a): Often used as a stationary phase in column chromatography, but not in paper chromatography.
2. Silica gel (b): Commonly used in thin-layer chromatography (TLC) rather than paper chromatography.
3. Narrow glass (c): Not applicable as a stationary phase in any chromatography format.
4. Cellulose (d): The primary component of chromatography paper, thus acting as the stationary phase in paper chromatography.

Verify and Summarize

In paper chromatography, the cellulose acts as the stationary phase that absorbs the components of the mixture, allowing for their separation as the solvent moves up the paper.

Final Answer

The correct answer is d. Cellulose.
