      Hi Kamilo12!
      Most salt comes in sodium chloride. Sometimes, people use potassium chloride as a replacement—it does not taste the same though. The reason to use potassium chloride is help people with high blood pressure some times caused by sodium chloride, because sodium chloride tends to retain water in the blood.
