of methanoic acid is constant throughout the experiment. method 1) Set up the colorimeter according to the instructions. Select a blue or green filter. 2) While you are waiting‚ prepare a results table with TIME in seconds and ABSORBANCE (in relative units). You are going to read the absorbance after 15‚ 30‚ 45 seconds‚ etc. until you have about 9 or 10 readings. 3) Fill a sample tube with distilled water and place in the colorimeter. Adjust the controls to give zero absorbance on the scale

Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial
