    September 20‚ 2010 EXPERIMENT Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pHs balanced and neutral? Information pH measures how acidic or alkaline a solution is. Its concept was introduced in 1909 by biochemist Soren Sorensen. The scale ranges from 0-14. Solutions that range from 0 to 6 are considered to be Acidic. Solution that’s on the Acidic end of the scale is low in ph‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid have a sour taste‚ reacts with metal‚ are

    Observing Enzyme Activity Purpose: The purpose of this experiment was to test whether the pH affected the enzyme reaction rate. Hypothesis: If the enzyme is in a basic solution‚ then it will react faster because the enzyme (catalase) reacts better in basic solutions. Materials: 10 potato cubes (1 cm3) -Pipet Baking soda solution -50 ml glass beaker Bleach Water Lemon juice Vinegar 5 glass test tubes Drying rack Timer Graduated cylinder Hydrogen peroxide Procedure:

    professor! I chose to discuss topic 2 this week. The topic is Discuss how buffers help to regulate body pH. The pH level in the blood is maintained by the kidneys and the lungs. The pH level on the blood should be at 7.4. In order for the kidneys and lungs to maintain this pH level it affects the buffers in the blood. The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize it so the body is

    AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones

    determining the effects of pH on enzyme activity show that as the independent variable‚ pH‚ increases the dependent variable‚ percentage transmission‚ decreases. This is shown in the results as at the lowest pHpH 4.0 the average percentage transmission is at its highest at 97%. At the highest pHpH 8.0 the average transmission is 78.5%. This is also supported from the graph as it produces a negative gradient showing that as the percentage transmission will decrease with an increasing pH. This happens because

    My topic for the science fair project is "The effect of temperature in energy loss in a basketball". Some of my subtopics for my project include the pressure air and height in a basketball‚ the material a basketball is made out of and the size of the ball. Different sports require different size balls to correspond with the correct bounce it needs to be used during the sport. Thats why you would not be able to use a tennis ball to play basketball because it is too bouncy and a soccer

    energy from our hands to the ice and the temperature difference between the two objects. The energy we are familiar with is called heat while temperature is the measure of a degree of heat or coldness of an object. In everyday life‚ heat or cold is commonly used to explain the degree of temperature of an object. An object that is said to be hot means it has a high temperature. Similarly‚ when an object is said to be cold‚ is means it is has a low temperature.  IMAGE GOES HERE Image Source Why
