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

It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are
