Can You Match The Flame Test Colour To …

09.09.2015· Zernliew / Getty Images. When you place a compound in a flame, the flame will change colour depending on the metal ion present in the compound. You can use the colour of the flame to work out what metal you have in your sample. This can be very handy if you''re a crime scene investigator, or a high school chemistry student trying to pass an exam.

experimental chemistry - Why flame color of …

29.05.2017· If a pure metal is heated up in a flame, we see it giving the flame a characteristic color, e.g. $\ce{Na}$ burns yellow. If a salt, e.g. $\ce{NaCl}$ or $\ce{Na2SO4}$, is heated up, resulting color to a greater degree still is that of the pure metal. Although the color does change depending on the anion, this effect is usually not much pronounced.

Flame Tests - Chemistry LibreTexts
