False. The most abundant negative ion in extracellular fluid is chloride, not calcium. Calcium is usually found as a positively charged ion in extracellular fluid.
Sodium ion is the most concentrated ion in the extracellular fluid.
There are many different answers. For example the most common, H2O also known as water. There is also H3O+, also known as a hydronium ion. There is also OH-, also known as the Hydroxide ion. I'm guessing that the answer to your specific question is H20, or water however there are tons of different answers.
