Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

BIOLOGY OSMOSIS LAB REPORT 1. Research Question/ Aim How do the different sodium chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be

of 6 M sodium hydroxide and about 1 mL of glycerol were added to each ingredient drop by drop then mixed thoroughly with a glass rod. The solution was then heated with a heating plate to boiling until it became pasty. After the paste cooled‚ 50 mL of saturated sodium chloride solution and ice was mixed into the solution. The soap was then filtered using suction filtration and washed with two 5mL portions of cold water. Each filtrate was saved separately. Two methods were used for making detergents. The first

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

1 The Limits of Amylase 2-1-14 Abstract This report explains the purpose of this experiment in a way that conveys information to the reader about Amylase’s ability to withstand acidic or basic pH. To do this‚ two test tubes were both filled with 5mL of a 5% amylase solution. The first one was filled with an acid‚ while the other was filled with a base. After dropping liquid Iodine and Benedict’s solution into each one‚ the tube with a basic pH tested positive for glucose. The acidic solution
