Objective: To successfully separate and identify all three unknown cations‚ found in a mixture and belonging to one of two specific groups (2 from one and 1 from the other). In order to do this we will be using various tests and reactions and observing the effect they had on our solution.

Discussion The four experimental techniques used in this proposal was aimed to complete the goal of answering questions about the system of three unknown red solutions. Based on the experiments conducted and the data collected‚ I am able to conclude information about the three red solutions that will lead to a possible identity of each red solution. Starting with red solution #1‚ we are able to conclude that there are no nanoparticles in this solution and that is a molecular compound due to the fact

Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we

Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts.

Conclusion Comprehensive marine and coastal databases are essential for management of the seas of Southeast Asia. Maps of resources found in marine and coastal environments‚ the sources of potential damage and data to guide managers are the means by which resources can be assessed and managed to maintain marine resources. This information is get by do the oceanographic survey. There is a strong need for data for managers to manage‚ conserve‚ remediate‚ recover and sustain continued use of Southeast
