Brine generally refers to saltwater, including sodium chloride, potassium chloride, etc. Of course, the brine used for making tofu is also called brine, but this is different.
Reply to 1# 1049492002: For the two-alkali industry, brine is natural groundwater rich in sodium chloride; just like coal and oil, it is a natural non-renewable resource. Underground brine is widely distributed in China, found along the coasts as well as in inland areas, in the south as well as in the north, and in the east as well as in the west. The taste of brine varies in different regions, and it also changes over time within the same region. Some can reach over 20%, while others only reach around 5%. High concentrations are useful, while low concentrations are not useful; such water is known as brackish water.
Brine refers to salt resources found underground. In cases where the salt content in natural salt deposits is not sufficient to be extracted through digging, water is injected to dissolve the salts, after which the solution is drawn up to obtain the salts for further processing. The main component of brine is usually sodium chloride solution, but it also contains various mineral salts such as potassium and magnesium salts. Brine is just a general term.
It should belong to mineral salts; its concentration is very high, much higher than that of sea salt. Nowadays, the chlor-alkali plants along the coast all purchase brine from the interior regions
