Final answer:
Sodium chloride, known as table salt when in a 0.9% solution in water, is referred to as normal saline which is used in medical treatments.
Step-by-step explanation:
Sodium chloride, also known by the chemical formula NaCl, is an ionic compound consisting of a 1:1 ratio of sodium and chloride ions. In the medical field, a specific concentration of sodium chloride in water, typically 0.9% is referred to as normal saline.
While sodium chloride is indeed the compound that makes up table salt, the term normal saline specifically refers to this isotonic solution that is often used in medical treatments to match the salinity of the human body. Therefore, the answer to whether Sodium Chloride is also known as normal saline is true but with an understanding that normal saline refers to the solution used in medical contexts.
