Marble Chips Experiment Pilot Aim: To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips. Prediction: I predict that the more hydrochloric acid there is the faster the chemical reaction. I also predict that the more dilute the acid is (the more water there is with the acid) the slower the chemical reaction. Hypothesis: I predicted what I did because the more concentrated the hydrochloric acid is the more energy there will be and
Gas Syringe  Glass Flask  Calcium Carbonate  Hydrochloric Acid Variable Factors The factors that could slow down or speed up this reaction are:  The size of the Calcium Carbonate (marble) pieces – This will affect how fast the acid reacts with the marble, the smaller the pieces, the bigger the surface area so the reaction can take place faster.  The amount of Calcium Carbonate – The more calcium carbonate there is, the more carbon dioxide will be produced

Investigation of the reaction between hydrochloric acid and marble chips A chemical reaction is when two or more substance called reactants are chemically bonded to form a new product, as a result of the process, for a reaction to take place, the particles must have enough kinetic energy to collide and form new bonds , this is called a successful collision. The minimum amount of energy needed for a successful collision is activation energy, which is “The energy that an atomic system must acquire

How the concentration of an acid affects the rate of reaction on marble chips Background: These different speeds of reaction are referred to as their rates. The rate of reaction depends on how often and how hard the reacting particles collide with each other. Particles have to collide in order to react, and the have to collide hard enough as well. This is called the collision theory. When the temperature is increased the particles all move quicker. If they are moving quicker then they are going
