The Effect Of Acid Rain On Building Materials

Extracts from this document...


Jason Goodwill Chemistry Coursework Investigation: The Effect Of Acid Rain On Building Materials Due to dissolved carbon dioxide rainwater is naturally acidic in the form of the weak carbonic acid. However gases such as sulphur dioxide and nitrogen oxides cause acid rain, which is responsible for the corrosion of buildings and damage to the wildlife. The burning of fossil fuels releases these gases into the atmosphere when the small quantities of sulphur react with the oxygen in the air, forming sulphur dioxide. The aim of this investigation is to investigate the way in which one factor alters the rate of erosion of building materials such as stonework and metals. To conduct this experiment I can use marble chips (calcium carbonate) ...read more.


of strips of magnesium) The factor which I have decided to investigate is the volume of hydrochloric acid. The range of volumes I have opted to use are 10cm�, 20cm�, 30cm�, 40cm� and 50cm�. The concentration of acid will remain at 2M throughout the investigation and the investigation will be conducted at room temperature. Also 1 strip of magnesium ribbon of mass 0.05g will be used throughout the investigation. For each volume of acid used I will time how long it takes for 50cm� of hydrogen gas to be produced and collected in a gas syringe. Apparatus Conical Flask (with bung) 100cm� gas syringe Scales Measuring cylinder Stopwatch Hypothesis I believe that as the volume of acid increases so will the rate of gas produced. ...read more.


The first volume of 2M hydrochloric acid, 10cm�, was measured out using a measuring cylinder and then added to the flask. Simultaneously the stopwatch was started and the bung was placed on the conical flask. When 50cm� hydrogen had been collected the stopwatch was stopped. This was repeated 3 times with each of the volumes of hydrochloric acid, 10, 20, 30, 40 and 50cm�. For each volume an average time was calculated and then using that time the rate of reaction was calculated with the following equation: Rate (cm�/s) = Volume of gas produced (cm�) Time (s) Results Time Taken (s) Volume of HCl (cm�) Reading 1 Reading 2 Reading 3 Average Reading Rate of Reaction (cm�/s) 10 111.41 98.78 101.85 104.01 0.481 20 70.54 61.82 69.39 67.25 0.743 30 48.99 58.48 56.21 54.56 0.916 40 45.39 55.90 44.78 48.69 1.027 50 43.16 26.41 35.69 35.09 1.425 ...read more.

    * Avoid inhaling the acid. Therefore the experiment should take place in a well ventilated lab. If inhaled and starts to irritate leave the lab for fresh air. * Sulphur dioxide is produced as a product in the reaction and it's toxic in high concentration and is a severe respiratory irritant at lower concentration.

    Repeat steps 1-8 with each set of volumes of solutions as shown in the table below. Volumes of solutions required when varying the concentration of bromide solution: Beaker X Beaker Y Volume of 0.01M KBr /cm3 Volume of deionised water /cm3 Volume of 0.005M KBrO3 /cm3 Volume of solution C

  2. Investigating how concentration affects rate of reaction

    results obtained when stirring by hand and when using the magnetic stirrer. However, when the mixture is left without stirring anomalies arise, as is shown in the table. There is a reliable trend until the concentration of 0.005mol/dm-3, where the time taken for the mixture to turn colourless decreases rather than increasing.
