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

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

the pH‚ oxidative reduction potential—or energy potential/activity—molecular structure‚ and purity. Science has helped us to determine that the best measurements for our drinking water are the pH and purity‚ but little understood is the importance of the molecular structure of water. Assuming that most waters that humans are drinking are purified‚ most tap and bottled water has 10 to 20 molecules per water cluster. The larger the molecular water cluster‚ the lower the electron activity. The
