The Formation of Alum Experiment 4 Introduction In an increasing population the need for land fields are as well increasing daily. Better yet‚ rather than dumping off trash is to instead recycle aluminum cans for a more efficient society. In this lab we will show how aluminum cans react to form alum. Materials and Methods The first step of the lab is to measure the mass of 250 mL beaker‚ once you have done this add .9 to 1.2 grams of aluminum can pieces to the beaker. Take the mass once

Linear Regression & Best Line Analysis Linear regression is used to make predictions about a single value. Linear regression involves discovering the equation for a line that most nearly fits the given data. That linear equation is then used to predict values for the data. A popular method of using the Linear Regression is to construct Linear Regression Channel lines. Developed by Gilbert Raff‚ the channel is constructed by plotting two parallel‚ middle lines above and below a Linear Regression

investigate reaction rates‚ and it is a reaction between acidified hydrogen peroxide and potassium iodide: 2H+(aq) + 2I¯ (aq) + H[-1] 2O2 (l) ÕI2 (aq) + 2H2O2 (aq) Iodide ions are firstly oxidised by the hydrogen peroxide‚ as shown in the above equation. The iodine that is then produced reacts immediately reacts with thiosulphate ions as follows: I2 (aq) + 2Na2S2O3 (aq) Õ 2NaI (aq) + Na2S406 (aq) As soon as all of the thiosulphate ions have reacted with the iodine‚ the excess iodine

Once the rate law is determined‚ the activation energy can be calculated using the Arrhenius equation. By using logarithms‚ the Arrhenius equation can be converted into the following linear equation: k = Ae-Ea/RT ln k = ln A- Ea/RT slope = -Ea/R Procedures: After following the usual lab rules and wearing personal protective equipment‚ we began by measuring out our solutions.

reactant or the rate of increase of the concentration of a product. The rate law is an equation that expresses the rate of a reaction as a function of the concentration of all the species present in the overall chemical reaction at some time. The rate law is often found to be proportional to the concentration of the reactants raised to a power. For the depolymerization of diacetone alcohol the empirical rate equation is -∂x∂t=kxn[OH-]m (1) X= concentration of diacetone alcohol ‚ t=time ‚ k=rate
