Chemistry is one of the branches of science, which is the study of compositions, behaviour of matter and their properties, chemical reaction and the changes that occur due to such reactions. This part of science has played a crucial role in enhancing and improving the living of human beings. However, chemistry is considered to be one of the toughest subjects. If you want to score good marks in your CBSE Class 12 board exams, you need to understand the subject properly, and we can help you with Chapter 12 of Chemistry with the help of NCERT Solutions for Class 12 Chemistry General Principles.

Let’s take a look at the contents of Chapter 6 of Chemistry- General Principles and Processes of Isolation of Elements.

In Chapter 5 General Principles of Chemistry and Processes of Isolation of Elements of Chemistry, you will learn –

After studying this chapter, you will be able to explain the various terms and understand their principles with the help of class 12 chemistry chapter 6 NCERT solutions.

6.1. In this section of Chapter 6 of chemistry, you will learn about the occurrence of metals. There are four principal metals which are iron, aluminium, zinc, and copper. We discuss these metals in detail the following sections.

6.2. Here the level of concentration of ores and the procedures that one needs to follow to remove unwanted materials from the ore are studied. The procedures mentioned in this section are hydraulic washing, magnetic separation, froth floatation method, and leaching.

6.3. For this portion, you will learn about the two ways of extraction of crude metals from concentrated ores. The extraction is essential as the concentrated ore needs to be converted into a form which is suitable for a reduction.

6.4. In this part of the chapter, the Thermodynamic Principles of Metallurgy is discussed. This principle has been thoroughly explained with the help of examples, and the application of Thermodynamic Principles for the extraction of oxides from the metals has also been explained.

6.5. The Electrochemical Principle of Metallurgy has been explained in this section of General Principles and Processes of Isolation of Elements.

6.6. Previously we have learned that it is essential to extract the impurities from the ore of principle metals. Here we will discuss the method of Oxidation-Reduction which is used for extracting impurities with the help of oxidation which is most used for non-metals.

6.7. In this section of Chapter 6, you will learn about refining. Refining is the process of obtaining metals of a higher level of purity with the help of several techniques. These techniques depend on the difference in properties of the metals and their impurities. The six techniques are also discussed in detail in this section.

6.8. Finally, for the last section, you will be taught about the various uses of the four principal metals, which are aluminium, iron, copper, and zinc.
