Answer to Question #166976 in Chemistry for Phyroe

Question

Indicate how concentrated H2SO4 for which is 18 F may be diluted to produce 300 ml of 3 F H2SO4-

Answer 1

As the 18 F acid must be diluted to produce 3 F acid, the dilution factor equals:

d = 18 F / 3 F = 6.

From here, the volume of the initial solution is:

V = 300 ml / 6 = 50 ml.

As a result, to make 300 ml of 3 F solutin, take 250 ml of water and slowly add 50 ml of concentrated 18 F acid.
