Schools are helping those rates grow by allowing fatty foods to be served as an option in cafeterias. School hour do provide what is missed during the day and the listed consequences. Thanks to some founders‚ schools are basically right next door to fast food restaurants. Children who can’t get their own money for food and rely on chores

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

During this experiment the change in pH of Citric acids is measured from start to equilibrium in mL. This experiment was tested by titration it had two separate trials. Through observations it was shown that the more concentrated acids needed more drops of NaOH to reach its equilibrium then the less concentrated acids. Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant.com‚ Feb. 12). NaOH

Date: 11/11/2012 Fast Food Contain Harmful Food Additives In America‚ fast food chains are a significant symbol of the American traditional food trends which expand widely and grow fast all over the world. Thus‚ a large number of Americans eat fast food as their daily diet. However‚ these tasty fast foods are highly processed foods which are filled with plenty of chemicals‚ additives and preservatives. By adding these additives and artificial flavorings into fast foods‚ so the food is attractive and

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.

A pH meter is an electronic device used for measuring the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. A colorimeter is a device used in colorimetry. In scientific fields the word generally refers to the device that measures the absorbance of particular wavelengths
