Solubility of Gas in Liquids — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Solubility of Gas in Liquids.

Combined effect of temperature and pressure on a real-world scenario.

high

NEET often tests the application of multiple concepts simultaneously. A question might describe a scenario (e.g., a diver at a certain depth and water temperature) and ask about the combined effect on gas solubility, requiring students to consider both Henry's Law and the temperature effect. For example, 'How would a diver's risk of bends change if they ascend from cold water to warm water at the surface?'

Graphical interpretation of Henry's Law.

medium

While direct numerical problems are common, NEET is increasingly incorporating graphical analysis. A question might present a graph of partial pressure versus mole fraction for different gases and ask to identify the gas with the highest/lowest $K_H$ or solubility, or to interpret the slope of the line. This tests conceptual understanding beyond mere formula application.

Quantitative comparison of Henry's Law constants for different gases.

medium

Instead of just asking which gas is most soluble, a question could provide $K_H$ values for several gases and ask for their order of solubility, or to calculate the ratio of solubilities. This requires a solid understanding of the inverse relationship between $K_H$ and solubility and careful comparison of numerical values.
