IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

Introduction: We are conducting this experiment to identify how temperature affects the solubility of salt. To add on‚ by making this experiment we could see how temperature affects the solubility of a substance‚ the maximum number of solute particles that can dissolve in solvent particles. Also‚ how by changing the temperature we could see how if the solubility of the solute would either increase or decrease. This experiment connects with information we learn in class because of how in class

Abstract Rhesus typing is an important clinical technique which involves finding out whether some ones blood is RhD+ve or RhD-ve‚ it is important to find this out as it can have serious health complications if blood that is un compatible is mixed‚ either during pregnancy or transfusions. This experiment involved using the techniques of PCR to amplify the DNA collected‚ using electrophoresis to separate the DNA and using markers and positive controls of known size to determine the size of fragments

Ocean Acidification SDI: Solubility of CO2 in different temperatures Aim: To observe the solubility of CO2 in different temperatures Hypothesis: We hypothesise that in cold water the level of co2 absorption will be greater than warm water which will mean the air space in the cylinder will be less compared to warm water. Independent: Type of water. Dependant: room temperature‚ amount of water‚ type‚ size and amount of tablet‚ amount of water in the basin. Materials: 250ml graduated

Germ Line Control of female Sex Determination in Zebrafish In order to identify the sex of a developing embryo‚ many scientists have studied this process called sex determination that allows them to have better understandings on how sex is being determined in either vertebrates or invertebrates. Sex determination is normally determined genetically; however‚ other factors can contribute to its determination. There are numerous determinants that control sex determination‚ but the most important are sex

Acid Determination of Vitamin C Tablets and Salt Solutions Chem 1290-016 03-05-2010 ------------------------------------------------- Purpose: The purpose of this lab was to use acid-base titrations to find the mass percent of ascorbic acid in a Vitamin C tablet. A known concentration of sodium hydroxide was used and the value found was compared to the stated amount of ascorbic acid listed on the vitamin container. Also in this lab the acidity of different salt solutions were tested using

at hand‚ and the determination that whether we win or lose‚ we have applied the best of ourselves to the task at hand.” Determination can be a characteristic used to describe someone based on their actions. Unlike other words that describe a person determination has a positive connotation attached to it. Every individual has a unique combination of characteristics that make up who that person is and what their work ethic or style is. The most common definition for determination is the unwillingness
