primary alcohols used were; methanol and ethanol‚ and the secondary alcohol was; isopropyl. Of this the secondary alcohol‚ isopropyl was discovered to be the most effect alcohol to make DNA precipitate‚ as it produced the most amount of DNA. This investigation of extracting DNA is significant due to the study taken providing understanding and knowledge on DNA; this allows people to find out information of the cell structure‚

Kinetics of the Persulfate – iodide Clock Reaction The purpose of this experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and
