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

Thermal Conductivity Heat can be transferred in three different ways: convection‚ radiation and conduction. Conduction is the way heat is transferred in a solid‚ and therefore is the way it is transferred in a heat sink. Conduction occurs when two objects with different temperatures come into contact with one another. At the point where the two objects meet‚ the faster moving molecules of the warmer object crash into the slower moving molecules of the cooler object. When this happens‚ the faster

such properties as electrical conductivity‚ lowering of the vapor pressure‚ refractive index‚ and sodium ion concentration remained identical in both the sol and the gel state. In support of their theory‚ Laing and McBain point out that Arrhenius (5) found the conductivity in gelatin-water-salt systems to be the same in both sol and gel. This aspect of the micellar theory has been extended by Gelfan (6) to protoplasm because he found that the conductivity of protoplasm remained independent

Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

Experiment Report Title: Water Conductivity Level in Goa Gajah Research Question: How high is the water conductivity level of the water sources in Goa Gajah? Hypothesis: I predict the level of electrical conductivity of the water sources in Goa Gajah will be between the range of a normal drinking water‚ which is 0.0005 to 0.005 s/m. This hypothesis is based on the fact that conductivity largely concerns itself with the amount of salt in the water‚ and since none of the water sources are

Lab Report Electrical Conductivity Introduction There are some substances that are capable of conducting electricity‚ and the reason they conduct electricity is because of the type of compound the substance is. Electrolytes or any ionic compound conduct electricity and nonelectrolytes do not conduct electricity. An Ionic compound is formed from the electrical attraction between anions and cations‚ typically a metal with a non-metal‚ except hydrogen. When an ionic compound forms‚ the anion
