Nuclear Chemistry - Result Question 7

####10. Carbon - 14 dating method is based on the fact that:

[1997]

(a) C-14 fraction is same in all objects

(b) C-14 is highly insoluble

(c) Ratio of carbon-14 and carbon-12 is constant

(d) all the above

Show Answer

Solution:

  1. (c) By carbon dating method

Age of wood =2.3030.693×t1/2log(N0N) [ ratio of C14/C12 in living wood  ratio of C14/C12 in dead wood ]

Hence, it is based upon the ratio of C14 and C12.
