Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

wound healing and recovery especially in severely wounded patients. One of the approaches for treating wounds is the use of biocompatible composites incorporated with antibacterial agent to improve wound healing and diminish the wound infection risk 2. Ion-exchange zeolite has gained attention due to its renewable nature‚ good biocompatibility and excellent

Design lab for the rate of reaction between Mg and H2SO4 Introduction: Increasing the concentration (in moles) of H2SO4 will increase the rate of the reaction when a ribbon of Mg is added to the solution. The rate of the reaction all depends on how strong the concentration of the solution is. Research question: Does altering the concentration of H2SO4 increase the rate of reaction when a ribbon of Mg is mixed with the solution? Variables: Independent Variable: The concentration of

Reaction Paper On The Ice is an engrossing and suspenseful movie about two teenage boys. The boys grew up together in the town of Barrow‚ Alaska. One morning the boys (Qalli and Aivaaq) set out for a seal hunt with a friend (James). An argument took place that ended up in a tragic accident. The boys (Qalli and Aivaaq) promised to keep this a secret. The community began asking questions‚ which brought them telling one fabrication after another which lead to feeling more guilt. Qalli had more

Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must
