Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

Anise oil was successfully able to be extracted from anise seeds during this experiment. It was done by first crushing the seeds‚ then placing them into a distillation apparatus. The distillation apparatus evaporated the liquid from the seeds‚ which was captured in a flask. Next‚ DCM was added to the distillate‚ which allowed the water to be separated from the anise oil. Finally‚ the DCM evaporated and the pure anise oil was collected. The process of steam distillation allowed the anise oil in the

Introduction 1.1 Background Information Acids are separated into different categories. These categories are strong acids and weak acids. Hydrochloric and Sulphuric acid are strong acids‚ and Phosphoric acid is a weak acid. When an acid is placed into water‚ it ionises (Tinnesand‚ n.d.). Ionisation occurs when the acid splits up into its two base components. So when Hydrochloric acid is placed into water‚ it splits into a hydrogen ion and a chlorine ion. The amount that an acid ionises depends on its strength

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde‚ 4-5% sesquiterpenoids (α-humulene‚ β-caryophyllene

1. Citric Acid * Citric acid is a weak organic acid with the molecular formula C6H8O7‚ which means a molecule of the acid contains six carbon atoms‚ eight hydrogen atoms‚ and seven oxygen atoms. When it is dissolved in water‚ it partially ionizes to yield three H+ ions (hydrogen atoms which are missing their electron) and a C6H5O7(3-) ion (the 3- means that it has three extra electrons.) The resulting solution is called an "electrolyte." Chemical Reaction When two dissimilar metals are put

becoming more and more acidic by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems
