5. The device used in this experiment only measured the relative conductivity of the solution tested, that is, whether the solution contained a strong, weak or non-electrolyte. A more elaborate conductivity meter can determine a numerical value that can be related to the number of ions in solution. Arrange the following 0.1 M solutions in order of increasing conductivity and explain why you chose this order. 0.1 M FeCl3 0.1 M MgCl2 0.1 M NaCl 0.1 M glucose (C6H12O6) 78.
Homework Answers
Conductivity depends on the following factors : Charge of ions, Concentration and electrolyte nature.
This is only valid for electrloytes i.e salts that form ions in solution meaning glucose has the lowest conductivity in this group.
According to charge, we get the order : glucose < NaCl < MgCl2 < FeCl3

In the following table, record the conductivity measured for each solution. The electrolyte type I should be strong, weak or non-electrolyte according to the table given previously. The species in solution should be a listing (in order of decreasing concentration) of the components of the solution. Ask your instructor if you need to list water as a species in solution.

Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
