What is the concentration of the salt water?

We are not unfamiliar with salt water, but if we really want to explain what kind of substance salt water is, we really can't explain it clearly. Salt water also has different concentrations, and salt water of different concentrations has different effects. For example, the concentration of normal saline used for infusion when we are sick is 1.03×10^3 kg/m3. Now let me introduce you to some information about salt water concentration.

1. Usually refers to seawater or common salt (NaCl) solution. Normally, the dissolved salt content in seawater is 35,000 mg/L (3.5%), including 20,000 mg/L of chlorides, mainly common salts, and there are also other types of brines, some of which contain 300,000 mg/L of dissolved salts.

2. Salt water is a glass of water with salt added, which is called salt water. As early as ancient times, ancient people had discovered the existence of this kind of water. Salt water can be used for disinfection and is a common item in our daily life. It is also what we use when we are sick, see normal saline.

3. Salt water has a wide range of functions. When there is dust or dirt in the home, you can splash some salt water on the dirty places to achieve a sterilization effect. The principle is to use the osmotic pressure of salt water to make bacteria lose water. In addition, if you sprinkle some salt water in the corners when cleaning your home, you can also prevent the invasion of cockroaches and other mosquitoes.

4. Sometimes we see some people soaking fruits in salt water for a while before taking them out to eat, which is also a good method. In fact, doing so can keep the fruit fresh and make it less likely to spoil.

5. If you use salt water to gargle, it can eliminate bad smell in your mouth and achieve a cleansing effect. It is said that drinking a glass of salt water when you have gastrointestinal discomfort can eliminate gastric acid in the stomach and achieve acid-base neutralization. In fact, the salt water may dilute the stomach acid rather than neutralize it, because the salt in the salt water is mainly neutral sodium chloride.

The above is some information about the concentration of salt water. I believe that everyone now has a certain understanding of the concentration of salt water. Salt water with a certain concentration has many functions and can be a good helper for us in daily life. As long as everyone is good at using it, it can serve us well.
