# FAQ’s on Salt Analysis in JEE

Joint Entrance Examination (JEE) is a common entrance exam conducted by Central Board of Secondary Education(CBSE). The JEE question paper is divided into three sections: chemistry, physics and mathematics. Chemistry is one of the most scoring subjects to enhance one’s rank in JEE. According to the JEE syllabus, chemistry is widely branched into three categories: inorganic chemistry, organic chemistry and physical chemistry. Of all these categories, inorganic chemistry is the easiest as the questions from this topic are knowledge-based and rarely test the analytical capabilities. One of the most important and difficult chapters of inorganic chemistry is salt analysis. Some FAQs related to salt analysis are underlined below:

Question: How to study“salt analysis” for JEE?

Answer: According to the JEE syllabus, salt analysis or qualitative analysis is related to the identification of cations and anions of salt by observing its behavior upon reaction with several species. This chapter mainly involves mugging up reactions and colors. Divide your syllabus for qualitative analysis in parts. Take one part, learn it by going through each and every reaction and don’t forget to learn colors and other special properties of these reactions. This process becomes very simple if you will try to imagine that you are actually doing the reaction. Make funny quotes on your own to remember the color changes. For example: for 5thgroup which is Ba+2, Sr+2& Ca+2 you can learn this as BATA SHOE COMPANY.

Question: What type of questions are asked in JEE from “salt analysis” chapter?

Answer: In JEE, the questions asked from salt analysis are direct and knowledge-based. You need to have the knowledge of reactions and the associated colour changes in order to predict the cations and anions.

Illustration:  A colourless solid X produces black spots on the skin. Aqueous solution of X gives brown ring test and gives a yellow precipitate with potassium iodide solution. The compound X is ____________.

1. Iron (II) Nitrate
2. Zinc Nitrate
3. Silver Nitrate
4. Sodium Nitrate

Aqueous solution of silver nitrate gives brown ring test and forms a yellow precipitate of silver iodide with potassium iodide solution.

$AgNO_3\;+\;KI$ $\rightarrow$ $KNO_3\;+\;AgI$

Questions: Which reference books can one follow for salt analysis?

Answer: While covering this topic you can take help of books such asVogel’s qualitative analysis. 15% of this book will be enough to cover all the topics enlisted in JEE syllabus. Apart from this, you must solve previous year question papers of JEE to cover this topic.
