You have prepared 1 liter of intravenous solution with 10 meq of CaCl2, 10 meq of KCl, and 9 meq of NaCl.

What is the concentration (meq/l) of sodium in the solution?

Answer :

The concentration of sodium (Na⁺) in the prepared intravenous solution is 9 meq/L.

To determine the concentration, we first need to look at the quantity of NaCl added to the solution.

Given data:

  • NaCl added: 9 meq
  • Volume of solution: 1 liter

We know that 1 meq of NaCl contains 1 meq of sodium ions (Na⁺) because sodium chloride (NaCl) dissociates completely in water to form Na⁺ and Cl⁻ ions in a 1:1 ratio.

Thus, the concentration of sodium ions in the solution is directly equal to the amount of NaCl added, which is:

Concentration of Na⁺ = amount of NaCl = 9 meq/L.
