Do forensic Scientists trace evidence?
Yes, forensic scientists analyze and trace various types of evidence found at a crime scene to help solve crimes. This can include analyzing DNA, fingerprints, blood spatter patterns, and other physical evidence to assist in criminal investigations.
Who to calculated normality of iodine?
Normality of iodine ((I_2)) can be calculated using the formula: Normality = Molarity x n, where n is the oxidation state of iodine in the reaction. For example, if you are using a 0.1 M (I_2) solution in a redox reaction where iodine is being reduced to iodide ions ((I^-)), then the normality of iodine would be 0.1 N.
How do you detect fingerprints on a frame other than iodine?
Other methods for detecting fingerprints on a frame include using ninhydrin, cyanoacrylate fuming, or fluorescent powder. Ninhydrin reacts with amino acids in sweat to produce a purple color, cyanoacrylate fuming involves exposing the print to superglue fumes to create a white residue, and fluorescent powders can be used with a UV light to make the prints glow for easier visibility.
How would you separate iodine crystals from mixture of iodine and sand?
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
Is there a method for detecting starch without using iodine?
Yes, you can detect starch using enzymes like amylase to break down the starch into simpler sugars, and then test for the presence of those sugars using a glucose test strip or a colorimetric assay. This method is often used in laboratories as an alternative to iodine staining.
What are common forensic techniques?
using aluminum powder or iodine to find fingerprints
3 different ways forensic scientists collect fingerprints?
Forensic scientists collect fingerprints using powders to reveal latent prints, chemical techniques to enhance prints on difficult surfaces, and physical lifting methods like adhesive tape to preserve prints for further analysis.
Why does iodine work when using to find fingerprints?
probably because iodine sticks to the oil from your fingers
How do you forensic scienctists find fingerprints?
Forensic scientists use various techniques to find fingerprints at crime scenes, such as dusting for prints with powder or using chemicals to reveal hidden prints. Once the prints are found, they are lifted and compared to known prints in a database for potential matches.
Do forensic Scientists trace evidence?
Yes, forensic scientists analyze and trace various types of evidence found at a crime scene to help solve crimes. This can include analyzing DNA, fingerprints, blood spatter patterns, and other physical evidence to assist in criminal investigations.
What makes fingerprints individual How do scientists match a fingerprint to a specific person?
Fingerprints are unique due to the intricate patterns of ridges and valleys formed by the skin on the fingertips, which are influenced by genetic factors and environmental conditions during fetal development. Scientists match fingerprints to individuals by analyzing specific features, such as ridge endings, bifurcations, and minutiae points, using both manual examination and automated fingerprint identification systems (AFIS). The uniqueness and permanence of these patterns make fingerprints a reliable method of identification in forensic science.
What are the advantages of being a forensic scientist?
Some advantages are that you get respect from the law and you should feel 'happy' that you have solved a murder or what ever you are doing that field. Also... you can get to work out who did the murder, and how, what is the murder weapon, and if it was a gun or a long distance weapon where it came from. X
Can you get fingerprints off cling flim?
Yes, it is possible to recover fingerprints from cling film, although it can be challenging. Fingerprints can be left on the surface of the film, and forensic techniques such as dusting with powder or using chemicals can enhance and visualize these prints. However, the success of recovering fingerprints depends on various factors, including the quality of the print and the conditions in which the cling film was handled.
What is a better technique than using Iodine to detect a fingerprint on a frame?
Charcoal dust is usually effective to detect fingerprints. If not you could try Fingerprint spray.
How does forensic identification work?
There are many ways to legally identify someone, living or dead. Fingerprints, the pattern of dental work, DNA analysis, distinctive tattoos or birthmarks, and many others; if you watch the TV series "Bones" you can see examples of how analysis of a skeleton can reveal many clues to the identity of the deceased person.
Can you fake fingerprints?
It is possible to fake fingerprints using various techniques such as lifting prints from surfaces or creating artificial prints. However, successfully fooling fingerprint scanners or forensic analysis is challenging due to the unique patterns and minutiae present in each individual's fingerprints. Engaging in such activities is illegal and unethical.
Can fingerprints be permanently removed using chemicals?
No, fingerprints cannot be permanently removed using chemicals.
