Who or what was to blame for the outbreak of World War Two? There were a number of underlying causes for World War Two’s outbreak in 1939‚ as with any big war there are whole tapestries of inter-locking reasons why everything happened the way it did‚ thousands of threads that sew into tragedies and victories and lead onto other wars and devastations. Undeniably‚ World War One and World War Two are very closely linked and the fact that the First World War ended so messily and left Germany in such

1. Question: How is the growth rate of bean plants affected by different types of water? 2. Introduction: We are going to be exploring the affect that different type of water have on the growth rate of bean plants. We will be experimenting with two different types of bean plants and testing three different types of water. PH is basically the negative log of hydrogen ion activity used to measure the acidity or basicity. The pH level ranges on a scale from one to fourteen‚ one being most

Experiment 3: Soil pH measurement Introduction Aims The aims of the experiment were to determine the pH of a variety of soils which included sedentary‚ 3:2‚ sand‚ organic matter with the means of a pH meter at various soil water ratios and with or without calcium chloride. Method and Materials Samples of sedentary soil‚ 3:2 soil‚ sand‚ organic matter and compost‚ 100ml vials(x12)‚ bottle of distilled water‚ analytical balance‚ pH meter‚ 2 buffer solution of known pH‚ 0.25M calcium chloride

Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides‚ this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution. Methods Verification of the Henderson-Hasselbalch equation

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of colors depending on its pH level was

II: Titration with a pH Meter 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. This amount must be different than the amount used in part I. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Insert the pH meter into the Erlenmeyer flask and record the initial pH of the acid. Remember to record the pH of the solution after

The Screen (ROUGH) In modern society‚ it is very uncommon to find someone who does not watch any form of video entertainment. Television is so common in the better countries in the world and society does embrace it in their everyday lives. If society was asked‚ “How much TV do they watch daily”? They may give a wide variety of responses. Some the answers may range in between one to possibly even over twelve hours a day!
