Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate

then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL of Acetic Acid at 50% (10 mL per run). • Vernier Temperature Probe.

In my experiment I have found that 50 millilitres of HCL with 2 grams of sodium chloride had the highest conductivity rate compared to the second most conductive solution‚ 50 milliliters of vinegar with 2 grams of sodium chloride‚ and the last conductive solution‚ 50 milliliters of distilled water with 2 grams of sodium chloride. In my first hypothesis I stated if I added sodium chloride to distilled water‚ than the overall conductivity will become more conductive than just distilled water‚ since

using different concentrations of hydrochloric acids (HCl) and indigestion relief tablet. I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion Tablet Indigestion is caused by excess acid in the stomach. The tablets neutralise some of this Acid and this is known as ‘Neutralization’

Hypothesis: The higher the concentration of hydrochloric acid‚ the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. The lower the concentration‚ the weaker the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: Conical flask – to hold the hydrochloric acid and marble chips Boiling tube – to hold and

____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First‚ the base was created‚ which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that‚ one by one‚ an aspirin tablet was dropped

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations
