Question

Why is it important for and iv solution to have salts solutes in it

Answer 1

you want the solution that's going to enter your bloodstream to have a similar solute composition (isotonic), otherwise you'll lower the concentration of the solute in your blood - in this case, salt.

Answer 2

Thus, the correct answer is - so the gradient is less steep to stops the blood cells from exploding.

Explanation:

An IV or intravenous solution is normally used to prevent dehydration when individual experiences dehydration and body of the individual loses fluids or if a person is not unable to eat or to provide medication directly to the veins.

IV solutions have salt solutes so the gradient should be less steep as if pure water directly enters the blood veins would cause blood cells to become hypotonic and explode which possibly leads to death.

Thus, the correct answer is - so the gradient is less steep to stops the blood cells from exploding.
