was done by examining the locations between multiple electrodes connected to a power source of DC electricity. Finding the lines of equal potential difference for two different 2-dimesioanl charge distributions. An equipotential line is a line that has a potential difference equal to zero. Using voltage probes‚ the equipotential lines found were sketched along with the lines that represent the electric field between the electrodes.

Oxidation Reduction Titrations: The Indirect Iodimetric Analysis Ascorbic Acid Unknown Number 69 I: Purpose: To determine the percent weight of Ascorbic Acid in unknown sample. This was to be done by the means of an indirect iodimetric analysis. In an iodometric analysis‚ the oxidizing agent can be determined by a different means than titrating directly with standard iodide‚ because a high concentration of I- is needed to form the I3- complex. In this type of analysis‚ excess iodide is added to

CHAPTER I Introduction Over 70% of the planet is covered by water. (75% of that is salt water‚ only leaving a 25% as fresh water which can be used for consumption. 70% of the fresh water of our planet is still frozen in the icecaps of Antarctica and Greenland; while the remaining percentage is present as soil moisture‚ or it lies underground as groundwater. Main Problem How can the seawater be utilized for the consumption of different organisms? Sub problems How will the results of the said

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac

Research Question How does changing the concentration of Zn2+(aq) ions (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1.0) (moldm-3) affect the voltage (V) of the voltaic cell consisting of Zinc and Copper half cells? Aim To see the relationship between increasing the concentration of Zinc ions and the voltage that is obtained from voltaic cell. The concentration of zinc ions can be directly manipulated by changing the concentration of a zinc sulphate aqueous solution‚ and the voltage will be measured using an electronic

DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

TOPIC 1: RATES AND CHEMICAL EQUILIBRIUM QUESTION 1: (Taken from the DoE Physical Sciences Feb-March Paper 2 2009) Antacids are used to relieve indigestion. Indigestion is the condition when the stomach produces too much acid resulting in an uncomfortable and painful feeling. A certain antacid tablet dissolves in water and reacts with the acid in the stomach to release carbon dioxide gas. 1.1 Name the type of chemical reaction that explains why antacids bring relief from indigestion
