What would a solution with 1.5% saline in it be considered as?

(c) Hypertonic

A saline solution with 1.5% saline would be considered hypertonic when going in the body. The blood in our bodies has a saline concentration of 0.9% on average. A hypertonic solution, for those who don’t know, is a solution that has more salt than what it’s going into. It’ll cause the salt in itself to move into the solution it’s going into (IE, your blood, if it’s a saline solution for your body).

Once the solutions equal out, the solutions would be considered isotonic. This is when two concentrations of a solvent (in this case, salt) are the same in two different solutions. Water will still move back and forth, as that is what the water does, but the salt will no longer move back and forth.
