    Cations and anions lab

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    This is a lab report that centers around the reaction between cations and anions. The resulting precipitate is indicative of the reaction that occurred. In our lab a lead nitrate solution, Pb(NO3)2 will be mixed with a solution of potassium chromate, K2CrO4, a yellow precipitate will forms.

    Though I have completed this lab, I am told that what I have is not sufficient and I know this is correct. Because I am not knowledgeable of the subject matter, I am not able to go into a great deal of detail. Out of of seven weeks of work, I have passed three labs with relatively good grades the rest have been 0-50 percent. I need help in bolstering the various sections of the lab.

    *****************

    I have taken a look at your attachment. Following are the suggestions that I want to offer:

    a. This is a double displacement reaction. You have to mention that.
    b. What is liquid precipitate? Just say yellow precipitate.
    c. You have shown a half-reaction, but not the overall balanced chemical reaction.
    d. Theoretical yield is 100 gm, not 100 ml

    CATIONS AND ANION LAB

    Introduction

    The purpose of this week's lab is to learn to demonstrate a double-displacement reaction of ionic compounds. To accomplish this, two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure, the product must be precipitated out of the solution and then weighed.

    For this lab, lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) ...

    Solution Summary

    Without writing the entire lab report for the student (which we are not supposed to do), this solution points out the mistakes and shows some specimen reports to follow.
