Experiment 4: Conductivity of electrolyte solutions (Dated: October 29‚ 2009) I. INTRODUCTION Pure water does not conduct electricity‚ but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound‚ which produces the ions as it dissolves‚ is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly‚ a weak electrolyte dissolves

electrical conductivity of electrolytes and non-electrolytes activity demonstrated the physical propertiesand the conductivity of some solution. Electrical conductivity apparatusare dipped into a liquid in a beaker. Whenthe liquid contains significant concentrations of ions‚ the ions more between the electrodes to complete the circuit(which includes a light bulb).Tapwater and distilled water are examples of non-electrolytes.

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

EXPERIMENT Ion - an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons. Ionization - The condition of being dissociated into ions by heat‚ electrical discharge‚ radiation‚ or chemical reaction. Electrolyte - A chemical compound that ionizes when dissolved or molten to produce an electrically conductive medium. Dissociation - When an ionic compound breaks up into its ions. The experiment started by placing the rods of the light bulb device into

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) b. Aqueous NaCl—Sodium Chloride

The blood plasma is consists of electrolytes. It comprise of both negative and positive charge. The negative charge is made up of chloride‚ bicarbonate and phosphates. The positive charge is made up of calcium‚ sodium‚ potassium and magnesium. This specifies the condition of the body’s acid-base ratio‚ water balance‚ endocrine and renal systems. These indicate the condition of your body’s acid-base ratio‚ endocrine and renal systems‚ water balance and other conditions. There is a fine line between

Chemistry December 14‚ 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity‚ then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any type of solution‚ even ionic solutions‚ provide resistance to the flow
