3 Title: Effect of 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.

The Effect of Soil pH on the Living Conditions In Lumbricus terrestris Abstract The difference in soil pH weighs a heavy measure on the appearance of the earthworm Lumbricus terrestris in different areas of soil. A highly acidic or highly alkaline soil may be the underlying reason for the absence of this earthworm in certain areas where pH plays a large role. In this experiment‚ soil pH was altered with Miracida soil acidifier and Agricultural Limestonea soil correctional for acidic soil

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

of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. 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

Effects of hyperventilation on CO2 and pH levels Alidrin Armandico Physiology Lab 142 Egle Ortega Aprill 25‚ 2014 Abstract The aim of this experiment was to analyze how pH and carbon dioxide (CO2) levels in the blood change during hyperventilation and how the renal system compensates for this condition. Hyperventilation decreases CO2‚ increases pH‚ and lowers H+ levels which then results to respiratory alkalosis. In the experiment‚ we used the PhysioEx 8.0 software to simulate hyperventilation

Enzymatic Activity of Salivary Amylase Abstract: Salivary amylase is an enzyme that can digest starch molecules and break them down to sugar molecules. In this experiment‚ the enzymatic activity and specificity of salivary amylase was examined depending on the changes in pH and temperature. In the first part of the experiment‚ the effect of temperature was determined‚ using constant temperature bath (4‚ room temp‚ 37‚ 50‚ 60‚ and 70°C). Having the room temp and 50°C as the highest and 37°C as infinite

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
