Conductivity Solutions
Abstract:
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 …show more content…
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 as distilled water will have a lower conductivity than the more dense solutions of mixed composition and elements which will create more of an electric …show more content…
The bar graph in Figure 1 describes the data collected by the conductivity probe throughout the experiment on the levels of conductivity in all the solutions tested by using the unit of microsiemens per centimeter (uS/cm). Results for the experiment include tends of very low conductivity in the sugars and some waters, such as Glucose 41 uS/cm, Sucrose 35 uS/cm, distilled water 60 uS/cm, tap water 365 uS/cm, and pond water 406 uS/cm. Ethanol was also low at 41 uS/cm compared to the other solutions Sodium Chloride 4,700 uS/cm, Calcium Chloride 8,400 uS/cm, Iron Chloride 1160 uS/cm and ocean water at 60,000 uS/cm. The solutions containing Chlorine were significantly higher in conductivity than other solutions due to the reason that Chlorine can create ionic bonds and polar covalent bonds. However, there was no significant difference between the tap and pond water, yet a large difference in the distilled water without the trace minerals and carbon dioxide that dissolves when water touches
