  • Drop In The Chips Into The Acid
    1,254 words
    Investigating the Rate of Reaction Between Marble Chips And HCL Safety- must always wear safety glasses and we should be very careful not to drop any acid. Fair test- we must make sure that we use the same size, amount and roughly the same mass of chips, this is because we want to keep the chips roughly the same all the way through the experiment so that it will be a fair test and the results we be in relation to each other, otherwise the results will be completely different to what we will expe...
  • Reaction Of Acid And Limestone
    1,479 words
    Aim In this investigation I am aiming to find out how the concentration of acid affects the rate of reaction with Calcium Carbonate (Limestone). Hypothesis I predict that the higher the concentration of acid then the faster the rate of reaction. Calcium Carbonate + Hydrochloric Acid = Carbon Dioxide + Calcium Chloride CaCO 3 + 2 HCl = CO 2 + H 2 O + CaCl 2 I predict this because when a chemical reaction takes place, the atoms are broken loose from their arrangements and re-arranged into differen...
  • Concentration Of Hydrochloric Acid In My Experiment
    1,121 words
    Scientific Knowledge There are many different factors that can effect the rate of a reaction, some of these are as follows: Temperature- The higher the temperature the more energy each particle will have which means it will vibrate more, causing the amount of collisions to increase. If the particles collide more, the rate of reaction is increased. Concentration of Acid- The higher the concentration of acid, the more partials there are to react with. If for example the concentration of Hydrochlor...
  • Second Lowest Concentration Of Hydrochloric Acid
    1,697 words
    ll What does the Concentration have on the rate of reactionWritten by Stephen Foster Brief: To investigate the factors that affect the rate of reaction between magnesium and hydrochloric acid. Introduction: I am to investigate what effects concentration of the reactant (hydrochloric acid) has on the rate of reaction between it and calcium carbonate. Specifically I am to see weather it will have an effect on the amount of the product produced and the time in which it took place. The Definition: T...
  • Reaction Between Magnesium And Hydrochloric Acid
    1,453 words
    Background Knowledge: Rate is a measure of how fast or slow something is. For example, Silver Chloride precipitating (this is a very fast reaction) and Concrete setting (it may take a couple of days for concrete to harden). Rate is a measure of the change that happens in a single unit of time. Any suitable unit of time can be used - a second, a minute, an hour and even a day. To find the rate of reaction, you should measure: The amount of reactant used up per unit of time or the amount of a prod...
  • Number Of Moles Of Hydrochloric Acid
    1,340 words
    My aim in this investigation is to analyse a solution of hydrochloric acid and calculate the concentration of acid it contains in gdm. Apparatus Solution of Hydrochloric Acid (HCL - 0.3 molar) Solution of Calcium Hydroxide Ca (OH) 100 cm Conical Flask Pipette (25 cm) Pipette Filler Burette Distilled Water Volumetric Flask Funnel Methyl Orange Indicator White Tile. Method 1. Collect all the apparatus and set up as shown in diagram below. 2. Hydrochloric Acid should be diluted. I have to dilute th...
  • Hydrochloric Acid As 3 Cm Of Magnesium
    654 words
    An Investigation into what effects the rate of reaction between magnesium and hydrochloric acid. Aim: My aim is to do an investigation into how the concentration of acid affects the rate of reaction with magnesium. I must consider; "h How much magnesium to use "h What concentration of magnesium to use "h Must react within a reasonable time Prediction: In solutions of higher concentration particles arse closer together. Which means they have a greater chance of colliding. Because there are more c...
  • Beginning With 25 Mls Of Hydrochloric Acid
    580 words
    The effect of concentration on the rate of reaction between magnesium and acid! Aim - To investigate how concentration effects the rate of reaction between magnesium and hydrochloric acid. Prediction - I predict that the weaker the hydrochloric acid is the slower the gas will collect. This is because in a weaker concentrated solution there is less acid molecules to react with magnesium. This is to do with the kinetic theory. Background information on reactions - The kinetic theory is in solution...
  • Ph Scale Acids
    367 words
    Acids Acid And Bases Conclusion: Acids appear in products people use every day. To start, an acid is a compound that releases hydrogen ions in water. In order to find out if a substance is an acid, one must test it with litmus paper and a pH scale. On the pH scale acids measure from 1 to 6, pH 1 being the most acidic (the highest concentration of hydrogen ions). One example of an everyday product that is an acid is lemon juice which is used for cooking. Lemon juice has a pH of 1, this means that...
