them where: what is the difference between an acid and a base; what is pH; what is equilibrium, what is Le Châtelier’s principle; and what is oxidation. Here are some of the things that I learned in lesson 07.01 (Acids and Bases) and lesson 07.02 (Acid-Base Reactions). An acid is a substance that produces hydrogen ions, H+ or hydrodium ionsH3O+ in solution. There are three “kinds of acids”: Arrhenius, BrØnsted-Lowry, and Lewis Acid. An Arrhenius acid is a substance the increases the concentration

I will gather the gas released from the fizzing and measure how long it takes to gather a certain amount of gas. Burette [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE] The light blue area represents the hydrochloric acid, and the white blobs are the limestone. The grey area is the carbon dioxide released from the HCl and
Acid Base Reactions Acid An acid is a substance which donates proton in water solution. They turn litmus red and form salts when they react with bases.They have PH less than 7. Examples: Nitric acid Nitrous acid Sulphuric acid Base A substance which accepts proton in water solution is called base. Bases turn litmus red and form salts when react with acids. They have PH greater than 7. Examples: Sodium Hydroxide Sodium bicarbonate Magnecium hydroxide Acid Base Reaction A chemical reaction that happens
The Rate of Reaction Of Metals with Acids Introduction In this investigation I will be looking at the rate of reaction between a metal, which will be magnesium ribbon, and an acid. The acids will either be hydrochloric, ethanoic, sulphuric or phosphoric acid. I will be finding out if the activation energy changes depending on whether a strong or weak acid is used. I will also be investigating whether or not there is a change in the order of reaction if a dibasic acid is used instead of a monobasic
The Effect of Acid on the Rate of Reaction with Magnesium Aim: To find out how the concentration of hydrochloric acid affects the rate of reaction with magnesium ribbon. Hypothesis: I think that the lower the concentration of Hydrochloric acid, the slower the rate of reaction with Magnesium ribbon. The reason why is because there are less particles in the same volume so less collisions are possible every second, therefore less effective collisions will occur. Preliminary work:
Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Aim To see the effects of concentration on the rate of a reaction between sodium thiosulphate and hydrochloric acid. Background information The collision theory briefly: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The
The Reaction of Sodium Thiosulphate with Hydrochloric Acid Plan ==== I am going to investigate the rates of reaction when sodium thiosulphate reacts with hydrochloric acid. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place: 1 [IMAGE] Seconds ------- There are five factors, which affect the rate of a reaction, they are:
The Effect of Acid Concentration on the Rate of Reaction Introduction: We are going to investigate the effect of Acid Concentration on the Rate of Chemical Reaction. We are going to use the combination of Hydrochloric Acid and Calcium Carbonate as the reactants: [IMAGE][IMAGE] [IMAGE]Calcium Carbonate + Hydrochloric Acid Calcium Chloride + Water + Carbon Dioxide Prediction I predict that the greater the concentration of acid the greater the rate of chemical reaction i.e. the rate
Sodium Hydrogen Carbonate and Acetic Acid Reaction Introduction Not knowing whether calculations on a paper or an experiment are conducted correctly is one of the problems faced in chemistry. Luckily to ensure both calculations are correct, getting a one hundred percent yield is a necessity. “The actual yield of a product as a percentage of theoretical yield,”1 is how to determine the percent yield of a reaction. Actual yield is the amount, in grams, that a reaction actually produces while theoretical
Reaction of Hydrochloric Acid and Sodium Thiosulphate In this investigation I am going to investigate how fast the chemicals Hydrochloric Acid and Sodium Thiosulphate react. The four main variables that affect rate are: * Temperature - if the reactants are heated/cooled they have more/less energy. If they have more energy there is greater chances of successful collisions meaning the reaction occurs faster. * Concentration - if the solution is more concentrated there are more reactants
Reaction Between Hydrochloric Acid and Magnesium Introduction In the reaction between hydrochloric acid and magnesium, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas. All chemical reactions involve reactants which when mixed may cause a chemical reaction which will make products. In my case the reactants are hydrochloric acid and magnesium ribbon. The chemical reaction

Planning; Aim To see how the concentration of acid affects the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate. Background; All reactions occur because of the particles that make up the reactants will collide, and if they have sufficient energy, react forming or breaking bonds. All four methods of increasing the rate of reaction can be
The Hydrochloric Acid, Sodium Thiosulphate Reaction Research: "Hydrochloric acid is a strong colourless acid formed when hydrogen chloride gas dissociates in water, used in industrial and laboratory processes. Hydrochloric acid is also produced in the stomach, where it initialises the digestion of proteins. Sodium thiosulphate is a white crystalline salt used as a fixer in photography and as a bleach." Encarta World English Dictionary When hydrochloric acid reacts with sodium thiosulphate
Reaction Between Hydrochloric Acid and Sodium Thiosulphate Introduction I will be conducting two experiments to determine how two factors affect the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate. It is a precipitation experiment. The equation allows us to see how this experiment will help us find how rate of reaction changes Sodium thiosulphate + Hydrochloric acid ---- Sodium chloride + Sulphur + Sulphur dioxide + Water Na2S2O3 (aq) + 2HCl(aq)
The Rate Of Reaction Between Magnesium And Hydrochloric Acid Aim My aim is to see how the rate of reaction between magnesium and hydrochloric acid is affected by changing the length of magnesium. Hypothesis I predict that if the length of magnesium is high then rate of reaction will be much more longer because if the length of magnesium is more then it will take longer to dissolve and therefore it will react for a longer time. Apparatus ========= o Measuring cylinders
The Reaction Between Hydrochloric Acid and Sodium Thiosulphate Introduction ============ I am investigating how different concentrations of thiosulphate and distilled water in ratio to 10cm³ of hydrochloric acid affect the rate of reaction. I will also investigate if there will be a change in temperature after the reaction has occurred. I will know when the reaction is taking place as the solution turns from clear to opaque. The reaction that takes place is as follows: - Sodium
Rates of reaction:- sodium thiosulphate + hydrochloric acid Plan:- We must produce a piece of coursework investigating the rates of reaction, and the effect that changing one particular variable has on the reaction time. The rate of reaction is the time it takes one or more of the reactants to react or the time it takes to produce a new product from a chemical reaction. To work out the reaction time we use the formula. 1 divided by time taken for reaction There are five factors which
Reaction between Magnesium and Hydrochloric Acid I am going to investigate how the concentration of the acid in the reaction affects the speed at which the gas, hydrogen, is given off. Magnesium + Hydrochloric acid -----> Magnesium chloride + Hydrogen Mg + 2HCl -----> MgCl2 + H2 Prediction I predict that as I increase the concentration of the hydrochloric acid, the speed the gas is given off will also increase. I think this
