We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is related to concentrations of ions and the speed with which ions diffuse through a solution. Faster-moving ions create higher conductivities and vise versa. If a solution is diluted the concentration of ions goes down, and the ability to pass a current is diminished. Therefore, the more ions or salt dissolved in solution, the higher the conductivity. Introduction:
Molecules and Ions are essential for life because they are found in all organisms. Molecules are the smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces. Ions are charged molecules or an atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. Conductivity is the measurement of the ability of an aqueous solution to carry an electric current. In this lab we produced conductivity tests to discover the differences between molecules and ions of various solutions such as Glucose, Sucrose, Ethanol, Sodium Chloride, Calcium Chloride, distilled, tap, pond and ocean water. The main point of the experiment was to test the hypothesis which is that distilled water has a decreased conductivity than other solutions. We wanted to find out specific data on these solutions in order to compare and contrast the differences and why the solutions resulted that way. It is predicted that solutions with more of a pure form such...
