The Qualitative Analysis of Ions – Competitive Exam Level section is designed to address conceptually tricky, reaction-based, and assertion–reason questions frequently asked in NEET, JEE (Main/Advanced), CUET, and undergraduate entrance examinations. This module emphasizes speed, accuracy, and deep conceptual clarity rather than routine laboratory procedures.
In this section, you will focus on:
Conceptual MCQs on group separation and selective precipitation
Ksp-based reasoning questions involving common ion effect and solubility trends
pH-dependent reactions and buffer control in cation analysis
Complex ion formation questions (NH₃, CN⁻, SCN⁻, etc.)
Redox-based qualitative tests and oxidation state logic
Interfering ion elimination in competitive question scenarios
Dry test and flame test MCQs with reasoning-based color identification
Assertion–Reason and multi-correct questions
Previous Year Questions (PYQs) with detailed explanations
Reaction prediction and elimination-based problem solving
The content is structured to train students to identify traps, apply chemical equilibrium concepts quickly, and solve qualitative analysis questions under time pressure.
Master Qualitative Analysis of Ions at a competitive exam level to convert this traditionally practical topic into a high-scoring theoretical area in Chemistry.
Q. In electrophoresis, what determines the direction of ion movement?
A.
Molecular weight
B.
Charge of the ion
C.
Solubility
D.
Temperature
Solution
The direction of ion movement in electrophoresis is determined by the charge of the ion; cations move towards the cathode and anions towards the anode.
