Chapter 19: Problem 7

Write short notes on (a) Alloy steel (b) Titanium alloys (c) van Arkel method (d) Ring test

Short Answer

Expert verified

Alloy steel is steel that contains certain elements providing better properties. Titanium alloys are made of titanium and other elements, known for their resistance to corrosion and lightness. The van Arkel method is a purification method used on metal ores where metal is heated with iodine. Ring test is a technique in chemistry for identifying ions in a solution.

Step by step solution

Explain Alloy Steel

Alloy steel is a type of steel that is made with a certain amount of other elements apart from iron and carbon. The inclusion of these elements can provide better mechanical properties to the steel, such as improved strength and durability, depending upon the percentage of elements and the method of heat treatment used.

Describe Titanium Alloys

Titanium alloys are metallic materials that contain a mixture of titanium and other chemical elements. These alloys possess properties like excellent resistance to corrosion, strength comparable to steel, but 45% lighter, and able to withstand temperatures from freezing point to over 400°C.

Discuss van Arkel Method

The van Arkel method, also known as the iodide purification method, is a technique to purify metal ores. In this process, the impure metal is heated slowly with iodine to form volatile metal iodides which when heated strongly, decompose to give pure metal.

Explain Ring Test

Ring test is a procedure used in chemistry labs to identify specific ions in a solution. When the solution of a certain ion is treated with a reagent, it forms a colored ring at the interface of two liquids. The color of the ring helps in identification of the ion.
