Solutions NEET Mindmap: Solutions chapter is one of the trickiest for NEET aspirants because it combines conceptual understanding with numerical problem-solving. It covers topics like molarity, molality, mole fraction, colligative properties, and Raoult’s law.
This chapter is trickiest as it gets difficult for students converting between different concentration terms or applying colligative property formulas in calculations. Solutions NEET Mindmap by PW present the concepts, formulas, and calculation steps visually, so you can link theory with practice effortlessly.
With the help of the mind map, you can see connections between concentration terms, colligative effects, and Raoult’s law in one glance, which is useful for solving NEET numerical problems under time pressure.

Solutions NEET Mindmap Practice Questions
Practicing questions is essential to prepare well for the Solutions chapter for NEET, as it involves both conceptual understanding and numerical calculations. Using mindmaps will help you visualize the links between formulas, concentration terms, and colligative properties. Below are the Example Practice Questions:
-
Concentration conversions: Convert 0.5 M HCl solution to molality, given the density of the solution.
-
Colligative properties: Calculate the freezing point depression (ΔTf) for a solution containing 2 mol of a non-electrolyte in 500 g of water.
-
Raoult’s law: Determine the vapor pressure of a solution containing 0.2 moles of solute in 1 mole of solvent, given the pure solvent vapor pressure.
-
Van’t Hoff factor (i): Calculate the osmotic pressure of 0.1 M NaCl solution at 298 K, considering complete dissociation.
-
Molecular mass determination: Using boiling point elevation or freezing point depression, calculate the molar mass of an unknown solute.
Topic-Specific Tricks Using Mindmaps
-
Mnemonic for conversions: “Moles in liters = M, Moles in kg = m” – visualize conversions as arrows in the mindmap.
-
Colligative properties linkage: Group ΔTf, ΔTb, and π together in the mindmap to remember formula patterns and units.
-
Electrolyte adjustments: Use color codes or symbols in the mindmap to distinguish when to apply the van’t Hoff factor (i).
-
Problem-solving shortcut: Start each numerical by identifying which term is given (M, m, or X) and trace the arrow in the mindmap to the target formula.
-
Real-life application cues: Connect osmotic pressure with biological examples like dialysis; ΔTf with antifreeze, so formulas are easier to recall.
