The Effect of Sodium Chloride on a Potato Chip To investigate what happens to a potato chip's weight when placed in different concentrations of Sodium Chloride INTRODUCTION:~ ============== Osmosis is defined as 'the movement of water molecules from an area of high water concentration to an area of low water concentration, across a semi-permeable membrane' (Collins, 1999). A semi-permeable membrane is a membrane that partially allows liquid to pass through. In the case of the experiment
DESCRIPTIVE TITLE The Effect of Different Amounts of Sodium Chloride on the displacement of oxygen. INTRODUCTION The dependability of the rate of an enzyme-mediated reaction is based on two factors: the substrate concentration and the concentration and action of the enzyme that catalyzes the reaction (Vander, et. al., 2001). Enzymes are catalysts that produce chemical reactions in cells. Enzymes which are large proteins perform a reaction which acts upon a substance known as a substrate. When
The Rate of Electrolysis Of Copper Chloride Solution Introduction We are going to find out what things affect the rate of Electrolysis and to find this out we will use Copper chloride salt dissolved in water to form a solution. The salt is dissolved in water becausechemical compounds when in a molten state or when dissolved in water exist in the form of ions that are capable of movement, meaning their molecules become dissociated into positively and negatively charged components, which
Lab Report for Experiment #2 1. The labels have fallen off of three bottles thought to contain hydrochloric acid, or sodium chloride solution, or sodium hydroxide solution. Describe a simple experiment which would allow you to determine which bottle contains which solution. The simplest experiment for this type of situation would be to use red and blue litmus paper to distinguish between acids, bases and salts. Hydrochloric acid (HCl) makes blue litmus paper change color going from blue to red,
Chemical Analysis of Preparing a Solution of Sodium Chloride One of the most common practices in the laboratory is accurately to prepare chemical solutions in the laboratory. I was given the task to prepare a one mole solution of sodium chloride for a precipitate experiment. The solution must be at a high level of accuracy to make sure the experiment works next week. Safety Points Sodium Chloride · Wear safety goggles · Do not eat · Use smallest amounts possible on a
Sodium Chloride on the Electric Current During Electrolysis Background When an electric current passes through sodium chloride solution, chemical reactions take place at both cathode and anode. If one passes through sodium chloride solution, there will be passage of ions moving through this solution. This results in positively charged sodium ions, which have been dissolved into the solution, moving towards the cathode and deposited there. At the same time, negatively charged chloride ions
Ammonium chloride caused the water to cool. This means that the Ammonium chloride drew energy from the water to help it dissolve. As a result of losing its energy, the water cooled down. Calcium chloride caused the water to warm up. This means that energy from the calcium chloride was released and the water absorbed this heat. As a result, the temperature of the water increased. 3. Since you are measuring the temperature of the water, let’s call that the system. Relative to the water, was this

The Effect of Sodium Chloride Concentration in Growing Medium on the Growth and Total Germination of Cress Seeds Scenario There are a number of things that can influence how/if a plant grows and germinate. These include; · Amount and intensity of sunlight. · CO2 concentration of the air. · Temperature and humidity of the atmosphere. · PH of the water and soil. · Salt concentration of the soil and water. · Quality of the soil, i.e. Minerals and nutrients. · Use of
An investigation into whether the voltage affects the amount of gas produced during the electrolysis of sodium chloride solution. Prediction: I think that hydrogen gas will be produced due to the half equation 2H +2e àH this will be produced at the cathode because opposites attract and the hydrogen ions are positive. At the anode I think that chlorine will be produced due to the half equation 2CL -2e àCL the chlorine ions are negative so they are attracted to the positive electrode. I also think
Chloromethane, more commonly referred to as methyl chloride, is an organic compound categorized as a haloalkane functional group. Functional groups are atoms that control how the molecule will react with other molecues. Haloalkane functional groups consist of a carbon atom with four single bonds and one of the bonds in occupied by an element in the Halogen family; in this case chlorine. The structural formula is CH3Cl. This formula effects some of the physical properties which include the boiling
The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through the center of the cell. This rod is surrounded by a mixture of carbon and manganese dioxide
strongly affects the rate as you will see in the results, so we have to try and keep it the same throughout the experiment. The reaction we are studying is very easy to monitor and time. All of the products in the solution dissolve into it (sodium chloride, sulphur dioxide and water), apart from sulphur, which makes the solution go cloudy, and forms a precipitate. This can be written down as s-1for example 15.7 s-1means 15.7 per second is the rate of the reaction. The rate is generally measured
alkenes, providing enantiomeric excesses that regularly reaching 90% and sometimes exceeding 98% . The chiral manganese complex Jacobsen utilized was [(R,R)-N,N'-Bis(3,5-di-tert-butylsalicylidene)-1,2- cyclohexanediaminato-(2-)]-manganese (III) chloride (Jacobsen's Catalyst). (R,R) Jacobsen's Catalyst Jacobsen's catalyst opens up short pathways to enantiomerically pure pharmacological and industrial products via the synthetically versatile epoxy function . In this paper, a synthesis of Jacobsen's
Reactions Between HCL and Marble Chips Planning I have decided to investigate the effect of different concentrations of hydrochloric acid on marble chips. I want to see how long it takes for 30cm of carbon dioxide to be given off once the acid and marble chips start reacting. I carried out a preliminary experiment to see what sort of time ranges I was going to expect because I wanted to get the concentration levels right otherwise I could have been waiting for a long time. I didn't have
a German chemist, improved Oersted's process by using metallic potassium. He was the first to measure the specific gravity of aluminum and show its lightness. In 1854 Henri Sainte-Claire Deville, in France, obtained the metal by reducing aluminum chloride with sodium. Aided by the financial backing of Napoleon III, Deville established a large-scale experimental plant and displayed pure aluminum at the Paris Exposition of 1855. Aluminum is a lightweight, silvery metal. The atomic weight of aluminum
similar to the dry cell we use today. The positive pole is a rode of carbon embedded in a black manganese dioxide (MnO2) and Carbon particles and the negative electrode is made of zinc. The electrolyte consists of a mixture of ammonium chloride and zinc chloride made into a paste. This sits in between the negative and positive electrodes, which acts as an ionic conductor. When the cell is in use, atoms of the Zinc in the outer case are oxidized, giving up electrons and forming zinc ions. Zn
1. Sodium Chloride has a higher boiling point than water, so when salt is added to water, the solution has a higher boiling point than pure water. The sodium ions and chloride ions present in sodium chloride disassociate and dissolve in water. These ions interfere with the dipole interactions that occur between molecules of water. The dissolved sodium ions and chloride ions require more energy to separate from the water molecules in the solution than the water molecules from themselves, so the boiling
