The Qualitative Analysis of Ions – Problem Set section provides a comprehensive collection of graded practice problems designed to reinforce conceptual understanding, logical reasoning, and systematic analysis skills. This module is suitable for Class 11–12 students, undergraduate learners, and competitive exam aspirants, helping them convert theory into exam-ready problem-solving ability.
In this section, you will practice:
Basic identification problems based on group tests and confirmatory reactions
Cation and anion analysis questions with observation-based reasoning
Mixed-salt and multi-step problems
Ksp, pH, and equilibrium-based reasoning problems
Complex ion formation and interference-related questions
Assertion–Reason, MCQs, and multi-correct problems
Case-based and reaction-sequence questions
Previous Year Question (PYQ)–pattern problems with detailed solutions
Problems are arranged from easy to advanced level, enabling progressive skill development and strong exam preparedness.
Regular practice with this problem set will help students identify patterns, avoid common traps, and solve qualitative analysis questions with confidence and accuracy in school exams, UG assessments, and competitive tests.
Q. What is the main principle behind the use of UV-Vis spectroscopy in qualitative analysis?
A.
It measures the mass of a sample
B.
It detects the presence of specific ions based on their absorbance
C.
It separates components based on their charge
D.
It identifies compounds based on their melting points
Solution
UV-Vis spectroscopy identifies compounds by measuring their absorbance at specific wavelengths, which correlates with the presence of certain ions.
Correct Answer:
B
— It detects the presence of specific ions based on their absorbance
