Rates of Chemical Reaction II Pre-Lab Summary: First we will set up the experiment as shown in Figure 2‚ and then we will fill the trough with room temperature water and record the temperature and we will also add the room temperature water to the buret until it is about 10ml from the top. If there are no leaks in the apparatus‚ we will add 10ml of KI to 15ml of distilled water in a 125ml flask. We will swirl the flask so that it achieves room temperature‚ then we will add 5ml of H2O2 and quickly

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely

3A Task 1 Aim: the aim of the experiment is to find the best temperature to ferment yeast at. Hypothesis: the yeast will ferment the best at 60 degrees Celsius. Independent variable: the temperature of the water the yeast is put in to ferment. Dependent variable. The amount of air bubbles the yeast produces. Controlled variable: the amount of yeast and glucose in each syringe. Uncontrolled variables: human error in counting. Materials : Plastic soft drink bottle cut to size Marking pen

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

Pakistan is an embattled state‚ but at the same time Pakistan and its people are also a misunderstood nation. This article is a contribution to the ongoing debate about implementing rule of law in Pakistan. Rule of law requires the unity of law which is mostly in the form of state law. Pakistan is a legally
