The rate of gas bubbles The independent variables Increasing concentration of hydrochloric acid: This is because the heat energy, which is supplied to the atoms, is converted into kinetic energy and therefore the atoms move and collide with each other causing reactions.
This means that energy is given out. When I set up the experiment I had to make sure the apparatus is tightly attached at the vulnerable points where some of the hydrogen could escape, like where the rubber tubing connects to the syringe.
Without this energy the bonds will stay together and will not break, meaning that no reaction will take place. Preliminary experiment I was suggested to use 20cm3 of hydrochloric acid and 5cm of cleaned magnesium ribbon, and take the volume of hydrogen in the syringe every 10 seconds for the preliminary experiment to.
This proves that magnesium is higher in the reactivity series than hydrogen. This will be changed by changing dilution factor.
Reactants with high surface area provide a greater binding surface for other reacting molecules, and therefore increase the number of successful collisions at any moment. Check with your doctor to see what Acid and magnesium essay right for you. The constants controlled variables The quantity of Magnesium metal used will be held constant by way of using equal lengths of Magnesium ribbons and equivalent weights in grams of powdered Magnesium metal.
I predict that as the concentration of the Hydrochloric acid increases, the time taken for the magnesium to dissolve decreases. Some people should take magnesium supplements on a daily basis.
As the temperature increases the speed and the power at which the acid particles hit each other increases, making the number of successful collisions with the magnesium strip increase. Magnesium is essential for strong healthy bones and teeth. Before I attached the rubber tubing on I made sure there is no air in the syringe, by pushing the inside bit right down until the line where I read from is at 0cm3.
Using the less reactive metals like zinc, aluminium, iron or lead enables me to test the higher concentrations like 3M or 4M because the reaction will go slower so I will be able to read the results off the syringe properly.
I chose this because I can make all the different concentrations of acid and I will be able to record it accurately. Magnesium is also a treatment for insomnia, menstrual problems, PMS, and muscle cramps.
As magnesium disappears from the muscles, calcium rushes in and the muscles tend to become tense or cramp.
Magnesium metal in form of a ribbon or powder reacts with acids rapidly than water liberating hydrogen gas. As is obvious by the graph the activation energy decreases by a considerable amount. Catalyst A catalyst is a chemical intended to increase the rate of a reaction.
They have found that heart attack victims have low levels of magnesium in their blood and heart muscles.
It is located in the second group called the alkaline earth metals. They can be especially beneficial during times of extreme stress or illness.
If magnesium ribbon is replaced with an equivalent weight of powered magnesium, does the rate of reaction between magnesium and hydrochloric acid double? TimeThe longer the magnesium is left in the Hydrochloric acid the longer it has for the reaction to finish, so therefore there will be a greater yield of hydrogen.
All the experiments have to be repeated at least two times to make an accurate set of results. This second group of metals is also less reactive than the alkali metals.
Magnesium is an important material that is a chief component in a number of high-tensile-strength, low-density alloys. Reactions only happen if the particles collide with enough energy.
As the concentration of acid increases the number of acid particles also increases, this will therefore increase the number of successful collisions with the magnesium. Get Full Essay Get access to this section to get all help you need with your essay and educational issues.
To show the effect of a catalyst on activation energy a dotted line is drawn to show how much energy is required if a catalyst was added. Another prediction that I have thought of is that even though an increase in temperature will affect the rate at which the reaction takes place, but at the end of it the same amount of hydrogen will be formed.
When particles get stimulated or increased in number, the reaction will increase in rate because faster collisions will take place making more successful collisions.Free Essay: Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid.
Reaction (rate) between magnesium ribbon and hydrochloric acid Essay Sample Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. How Does Hydrochloric Acid Affect The Time Of Magnesium to Dissolve?Aim:To find the relationship between the concentration of hydrochloric acid and the time taken by Magnesium to mint-body.com:Rates of Reaction -Factors that alter speed of reactions/5(1).
magnesium (Mg) is known as a chemical element with the atomic number of Hydrochloric acid (HCL) is a strong, colorless mineral acid used with many purposes. Magnesium (Mg) is known as a chemical element with the atomic number of The silvery white solid is an abundant element found in the.
That means that I can have one conclusion on the investigating the effects of temperature on the rate of reaction between hydrochloric acid and magnesium: An increase in the temperature = an increase in the rate of reaction.
Reaction Between Hydrochloric Acid and Magnesium Essay - 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 .Download
