Sodium - Periodic Table of Elements and Chemistry

Sodium is a soft, silvery-white metal. It is soft enough to cut with the edge of a coin. Freshly cut surfaces oxidize rapidly in air to form a dull, oxide coating. Sodium burns in air with a brilliant yellow flame. Sodium floats on water, because its density is lower than water’s.

Why is platinum wire used in flame test for testing

Also, a platinum wire should be thoroughly cleaned before using it for a new flame test. A platinum wire is cleaned by dipping it into concentrated HNO3 and then placing it in the non luminous part of the bunsen flame. Otherwise, the perviously tested radicals will impart color to the flame, which may cause confusion.

How to Do a Flame Test for Qualitative Analysis

The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. Every element has a signature emission spectrum that can be used to differentiate between one element and another.
