Quizplus · Accepted Answer

The correct sequence for visualizing latent prints with these chemicals is iodine fuming first, as it is a non-destructive process and can be followed by other methods. Ninhydrin is used next for its ability to react with amino acids producing a purple color, and finally, physical developer is applied as it can reveal prints on wet or washed surfaces, making it the last step due to its potential to alter the evidence.
