September 10th‚ 2013 EXPERIMENT 1 LEARNING BASIC OPERATIONS: THE EFFECT OF PH ON A FOOD PRESERVATIVE Purpose: The purpose of this experiment was to investigate a competitor’s claim that the food preservative‚ sodium benzoate (C6H5COONa)‚ made by Fresh Foods International (FFI)‚ changed into a new substance in stomach acid. Stomach acid has a pH between 1 and 3 due to the hydrochloric acid content. Based on the net equation given in the book as well as the solubility of the product our hypothesis

The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze and convert molecules into combinations of other molecules which is necessary for the functions of human life. These enzymes are affected

dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer‚ pH chart. Substance of risk Nature

IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

I. EXECUTIVE SUMMARY This paper studies the fruit juice market in the Philippines. The market has experienced significant growth in recent years primarily owing to the craze toward health-food consumption. However‚ the relatively higher prices of fruit juices compared to other types of beverages have limited the consumer base to a small percentage of the population. Furthermore‚ various factors such as high packaging costs‚ seasonality and unavailability of raw materials‚ and inadequate transportation

It is a small‚ black fruit that contains a large seed at its center surrounded by small amount of pulp. The Acai Berry has the looks of a grape in both size as well as appearance but contains lesser pulp in comparison. The historical usage of Acai can be traced back to hundreds of years when people living in the Orinoco basin
