What is isotopic tracer technique?

Answer Posted / subhadeep biswas

An isotopic tracer is used in chemistry and biochemistry to
help understand chemical reactions and interactions. In
this technique, one or more of the atoms of the molecule of
interest is substituted for an atom of the same chemical
element, but of a different isotope. Because the atom has
radioactive property, so it can be detected separately
from the other atoms of the same element. And as it the
same compound, it will not interfere with the reaction
under investigation.
