Increasing or Decreasing the Concentration of HCL on the Speed of Reaction between HCl and CaCO3 Coursework HCl + calcium carbonate ® calcium chloride + carbon dioxide + water. HCl(aq) + CaCO3(s) [IMAGE]CaCl2(aq) + CO2(g) + H2O(l) Aim The aim is to investigate the effect that increasing or decreasing the concentration of the HCL has on the speed of reaction, between HCl + CaCO3. We will determine the speed/ rate of reaction by measuring the amount of CO2 given off in a set time

Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips Introduction ============ There are many factors that will affect the rate of reaction between hydrochloric acid and calcium carbonate. Some of them are as follows: * Temperature - If the temperature is higher, then the molecules in the solution have more energy, causing them to move around more which would mean they would react faster. * The surface area of the calcium

During this experiment carbon dioxide is produced. This is what we are going to use to record the speed of reaction, for the faster the reaction the

Investigation looking At the Speed of Reactions Introduction The aim of this experiment is to find out how a variable can affect the results from a scenario set up in scientific environment. The experiment is to see how a certain variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent. When compressed or exposed to great heat the mineral binds together

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

Concentration and Temperature Affects the Rate of Reaction between Magnesium Ribbon and Hydrochloric Acid. WHAT I AM INVESTIGATING I am going to investigate how concentration and temperature affects the rate of reaction between magnesium ribbon and hydrochloric acid. MY PREDICTION The thing which I expect to happen is the more acid added to water the faster the reaction will happen. Also the hotter the solution the quicker the reaction will happen. THEORY TO BACK UP PREDICTION

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

group I etc). Elements within the same group similar chemical properties but often show a systematic variation in extent or speed of reaction as the group is descended. For example all of the group one elements (the alkali metals) react vigorously with water to form water soluble alkalis with the subsequent production of hydrogen gas. However, the speed of reaction increases down the group (lithium only reacts relatively slowly with water but francium and rubidium are explosive in the

of the yeast will increase in speed as the temperature of the water increases. However, it may reach a peak, and slowly decline as the temperature increases further. My reason for the above prediction is that, anyone who has cooked, knows that yeast is supposed to respond in warm water, so I believe that the warmer the water, the more bubbles of CO² produced. Also, the oxygen produced in the initial stages of the experiment will allow the speed of reaction, of converting glucose to energy

Investigating the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid I predict that the higher the concentration then the faster the reaction, this is because when water is added the sodium thiosulphate solution and the hydrochloric acid have a more neutral pH and it becomes more dilute then it will be less reactive will the other particles in the solution. Equation for my experiment: [IMAGE]Sodium thiosulphate + Hydrochloric acid Sulphur + Sodium chloride Sulphur dioxide

Affects The Speed Of A Chemical Reaction Aim --- To investigate the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. Preliminary Research -------------------- The rate of a chemical reaction is the measure of how fast the reaction takes place. In a reaction particles must collide and overcome the fixed amount of energy for the reaction to take place. This energy is called the activation energy. The rate of reaction depends

Introduction: A chemical reaction is a process in which one or more substances are converted into other substances (Brown et al. 2015). The speed of a chemical reaction is called the reaction rate (Brown et al. 2015). The reaction rate is the change in the concentration of reactants or products per unit of time (Brown et al. 2015). Sometimes it is possible to measure the rate of reaction by timing a change in appearance (Van Norman 1963). Activation energy is the least amount of energy needed to

Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different

How the Concentration of Sodium Thiosulphate Influences Speed of Reaction with Dilute Hydrochloric Acid Aim: I am investigating how the concentration of sodium thiosulphate influences the speed of reaction with dilute hydrochloric acid. Equipment ========= * 1 piece of paper with a cross on it * 1 timer * 1 conical flask 100ml * 1 test tube brush * 119ml Sodium thiosulphate * 14ml 100% Hydrochloric acid * 1 beaker 400ml * 1 beaker 10ml 1. Working with the first

Investigating the Effect of Concentration on the Speed of the Reaction Between Hydrochloric Acid and Sodium Thiosulphate Prediction: My prediction is, the higher the concentrations, the faster the reaction will occur in my experiment to make the x on the sheet on paper disappear. When there is more concentration, the molecules gain kinetic energy & the process of collision occurs. This causes the reaction to happen more rapidly therefore making a cloudy substance much quicker. Hypothesis

Rates of Reaction Reactions Reactions can only occur when two different particles come together. The theory for the way the reaction occurs is called The Collision Theory. The collision theory states that that the different particles need to collide with each other in order to react. However, they do not react if they collide without sufficient energy, and therefore the more energy a particle has, the more likely it is to react. The activation energy is the minimum amount of energy

that studies the speed at which a chemical reaction occur and the factor that influence this speed. What is meant by the speed of a reaction is the rate at which the concentrations of reactants and products change within a time period. Some reactions occur almost instantaneously, while others take days or years. Chemical kinetics understanding I used in the process of designing drugs, controlling pollution and the processing of food. Most of the time chemical kinetics is used to speed or to increase

chemical reaction that happens when the tablet starts to dissolve in water. You’re probably wondering what makes up these tablets? Well, it is mainly citric acid, aspirin and sodium bicarbonate. The sodium bicarbonate dissolves into the water and when it does dissolve it splits apart into sodium and bicarbonate ions. The bicarbonate
