Cobalt 60 Mode of decay: Beta particles and gamma radiation Chemical properties: Metallic solid that can become magnetically charged What is it used for? Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation (http://www.cdc.gov/ncidod/dbmd/diseaseinfo/ foodirradiation.htm)‚ a sterilization

The Effect of pH on a Food Preservative September 18‚ 2012 Objective: To study the affect of pH on a food preservative. Chemical Equation: C6H5COONa + HCL ------ C6H5COOH + NaCl Procedure: This experiment was started with a clear solution of sodium benzoate and HCl was added to it‚ ultimately producing benzoic acid. First‚ .3395 g of sodium benzoate was weighed‚ then it was dissolved in water‚ causing it to disassociate into ions. Next‚ 3M of HCl were added drop wise to the solution
