Question

Save Question 3 (2 points) Pretend that HF is medically interchangeable with NaCl in an I.V. solution. In the "Chemistry Link to Health - Electrolytes in Body Fluids", we see that 154 mEq/L of Na+ and Cl-are each present in 0.9% 11. solutions. If you prepared your own simple 0.9% 1. solution at home, would you add the same amount, more, or less HF to your solution in order to attain this 154 mEq/L of cations and anions needed? Explain your answer. Recall that HF is a weak electrolyte. ± Font Far Size

Explanation / Answer

We need to add same amount HF to solution in order to atain the 154 mEq/L of cation and anion needed.

As the HF is weak electrolyte, don't dissociate completely and set up the equilibrium form.

And both NaCl and HF have ions with same valancy.
