So what are the unique and interesting chemical phenomena in our life?

You may think that chemistry is too far away from our life. In fact, chemistry is ubiquitous and ubiquitous in our daily life. So what are the unique and interesting chemical phenomena in our life?

What are the chemical phenomena in life

1. Kosher salt gets wet easily
   Principle: because salt is the salt of high purity, and salt is the main chemical composition of the sodium chloride, sodium chloride itself will not absorb moisture, so refined salt to place a long time, also won’t become wet, but composition of salt in addition to sodium chloride, also contains impurities such as magnesium chloride, calcium chloride, and magnesium chloride and calcium chloride which absorbs water easily, so coarse salt is easy to become wet;
2. The fire fanned up
   Principle: because to fan the fire, will speed up the flow of air, so it provides enough oxygen, so that coal and oxygen contact area increase;

3, steamed bread with soda ash
Principle: Because the flour fermentation will produce acid, add soda, can neutralize its acid, and can produce carbon dioxide, thus making bread loose porous, taste better;

1. The candle goes out when it is blown out
   How it works: Because blowing makes the air cold, the temperature of the candle falls below its ignition point. Once the temperature of the object does not reach the ignition point, it cannot burn, so the candle goes out.
2. Put desiccant in the food bag
   Principle: put desiccant in the food bag, mainly in order to absorb the moisture and oxygen in the bag, by preventing the breeding of microorganisms, to inhibit food moisture and deterioration.
