effect that the concentration of a solue has on the conductivity of an electrolytic solution. If NaCl is added to water to create an electrolytic solution then it will create a stronger electrical current than distilled water because NaCl is a strong electrolyte that can conduct electricity well due to its ability to dissociate into ions. Materials and Methods: In order to test for the effect that the concentration of a solute has on the conductivity of an electrolytic solution. Four beakers were filled

This is due to its covalent bonds‚ but when added to water the acid releases some of ions that allow for little conductivity. The chemical reaction of the disassociation of Formic Acid: HCOOH(aq) H+(aq) + COOH-(aq) d.

good a material is at conducting heat is known as its thermal conductivity. Thermal conductivity is defined as the rate at which heat flows through a certain area of a Object of the experiment is to determine the thermal conductivity of metals and insulation body.materials and also to demonstrate that heat flow is directly proportional to temperature differences between faces and to cross sectional area. Thermal conductivity is defined as:

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

Determining the Molarity of Acetic Acid in Vinegar Abstract This experiment was done to determine the molarity of acetic acid in vinegar. The acetic acid in vinegar was titrated with a strong base sodium hydroxide to determine the equivalence point of this chemical reaction. The indicator phenolphthalein was used because the moment it changes color is on the basic side of the pH scale. To insure the experiment was done with the most accuracy‚ the two conductors of this experiment took three

Introduction This experiment tests electrical conduction. Electrical conduction is the transportation of an electrical charge through a substance. This is done by the electrical charge/current being sent through the substance via electrons. These electrons carry the electrical current/charge throughout the substance’s length until another conductor is able to receive the electrons charge.
