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

order to discover the activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic

Concert Report The performance from Ashton Smith was quite impressive to say the least. To be honest I was never interested in classical music; let alone people who sing it.

I was absolutely clueless of the preparation that singers do in order to perform to the peak of their abilities. For example‚ when

He could read the doubt and fear on my face‚ but wasn’t ready to give up. “Mrs. Webster has that farm that we can see off the back deck.

The relatively close pH levels of Tap Water‚ Spring Water‚ Flavored Water‚ and Seltzer Water. Introduction This experiment was performed to investigate the following hypothesis: The following four different types of drinking water (spring water‚ seltzer water‚ tap water‚ and flavored water) we test will relatively have the same pH level. Our group decided to test different types of drinking water to see if a pH level of tap water is comparable to other types of water. Many people believe
