Hydrochloric acid (HCl): Hydrochloric acid is a strong and corrosive acid that is often used as a reagent in laboratories. It is made by dissolving hydrogen chloride in water. 17 Hydrochloric acid is polar substance and has a linear shape with an electronegativity difference of 0.9; it has weak dipole-dipole forces/bonds between its molecules (intermolecular forces) and polar covalent forces/bonds between the chloride and hydrogen ions (Intramolecular forces). (5) HCl has a molar mass of 36.4609
Observations and Explanation: When the hydrochloric acid was poured into marble chips, gas bubbles were seen – signifying the carbon dioxide (gas) that was being produced due to the chemical reaction. As the reaction was taking place, the water in the measuring cylinder was being displaced – indicating that the calcium carbonate (in the form of marble chips) was displacing the hydrogen in the hydrochloric acid. Discussion: According to the results shown, 2 M hydrochloric acid that was more concentrated had
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
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
Investigation into the Reaction Between Marble Chips and Hydrochloric Acid Planning ======== Introduction ------------ In the reaction between marble and hydrochloric acid, calcium carbonate particles from the marble react with the hydrogen chloride particles in the hydrochloric acid producing calcium chloride, water and carbon dioxide. The formula for this reaction is: CaCO3 (s) + 2HCl (aq) ® CaCl2 (s) +H2O (l) + CO2 (g) Choosing the variable ---------------------
The Rate of Reaction Between Hydrochloric Acid and Marble Chips Plan In this experiment, I will be investigating the rate of the reaction between Hydrochloric Acid (HCl) and marble chips. To do this, I will change the concentration of the HCl and measure how that affects the amount of CO2 produced during the reaction, and hence, find the rate. I predict that when I increase the concentration, the rate of the reaction will increase. I think this because of the particle theory. When the
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium Aim To investigate if the temperature of hydrochloric acid will affect the rate of reaction between hydrochloric acid and magnesium. Magnesium Ribbon + Hydrochloric Acid → Magnesium Chloride + Hydrogen Mg + 2HCl → MgCl² + H² Hypothesis I think that as the temperature of the hydrochloric acid increases so will the rates of reaction. I think this because of the Collision

The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid I am going to be investigating the effect of varying the concentration of Hydrochloric acid on the rate of reaction between Sodium thiosulphate and Hydrochloric acid. Chemical reactions can be affected by: Ÿ Changes in the surface area of solid reactants Ÿ Changes in concentration Ÿ Changes in pressure (with gases) Ÿ Changes in temperature Ÿ Catalysts
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 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 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 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.

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

The purpose of the experiment is to see how different volumes of Hydrochloric Acid affect the rate of reaction. The reaction, which produces solid Sulfur, it will then be followed by measuring the time needed for the reaction to become opaque/cloudy. Hypothesis: I predict that the higher the volume of concentrated Hydrochloric Acid the less time it will take for the cross to disappear. This experiment has
Hydrochloric acid is the clear colourless solutions of hydrogen chloride (HCl) in water, hydrochloric acid is also a highly corrosive substance and a strong mineral acid meaning they are formed from inorganic compounds, hydrochloric acid is a monoprotic acid meaning that it can only ionize one H+ ion. As a result hydrochloric acid can be used in a wide range of industrial practices such as removing rust from steel, ore processing, the production of corn syrup and making of PVC plastics. Hydrochloric
