My problem is:
I will dry a salt together with some other chemicals (some proteins, lipids). It will appear as a thin film after drying.
I am searching for a salt that will go in solubility in blood/plasma almost instant after blood/plasma is added.
So far I have tried NaCl and NaNO3 , however these salt have to slow kinetics when they go into solution in blood/plasma.
Do you have any suggestion for salt for this purpose???

Instantly? Try KCl, I think it might have better solubility.

Do these salts have to contain ions which are found naturally in blood and are not toxic?
