Does salt burn?

In this brief guide, we will answer the question “Does salt burn?” and tell you why salt does not catch fire. We will also discuss whether you can use salt as a fire extinguisher or not and if seawater can be used as a fire extinguisher. We will also tell you why the color of flame changes when you add salt to it and discuss whether salt melts or not.

Does salt burn?

No, salt does not burn. Salt needs extremely high temperatures to catch fire. Many of us at some point would have wondered if salt can catch fire because it is probably the most common staple found in everyone’s kitchen.

The good thing is that it does not catch fire, it is inflammable. The extremely hot temperature required to put it on fire is so high that it is not possible to reach that temperature in your kitchen. 

What makes salt inflammable?

Salt is inflammable due to its chemical composition. Salt is made from sodium (Na) and chloride (Cl). Sodium has a positive charge while chlorine has a negative charge. They come together and form a very strong ionic bond which needs very high energy to break it. It is not possible to easily break such a strong ionic bond.

Now, sodium and chloride individually are very reactive. It is only when they are bonded together so strongly, they do not react as easily. 

Can you use salt as a fire extinguisher?

Well, salt is not combustible and it does not even catch fire, so technically it can put out fires. It cuts off the supply of oxygen from the fire so the fire eventually dies out. However, it is not ideal as you would not have enough salt in your kitchen at all times to put out a fire. So, it can be used to put out a minor kitchen fire.

This is similar to smothering the fire with blankets or towels. 

Some people also sprinkle some salt over coals in a barbeque to calm down the fire a little.

You should call firebregrades in case of fire to be safe.

Why does the color of flame change when you put salt in it?

Have you ever seen a magician change the color of fire and wondered how that happened? They do that by putting salt in it. When you put salt in an open flame, it changes color to bright yellow. This is not because the salt is burning, but because when salt is added, a great deal of energy is released and a chemical reaction takes place which makes the color change.

If you put out this fire, you will notice that the salt will be intact, it would not have burnt at all. 

Is pink salt flammable?

No, pink salt is not flammable either. Pink salt has a few extra minerals but it is much like table salt only. These few extra minerals do not alter the chemical composition enough for it to catch fire. 

Can salt water be used to extinguish fire?

Salt water can be very effective in putting out fires. It is also said that seawater can be used to put out fires since it is so salty. However, salt would erode and make the equipment rusty so that is why it is not used.

Does salt melt?

Yes, salt melts at a very high temperature. The temperature required to melt salt is 800 degrees C. Such a high temperature can not be reached in your kitchen.
