A Reaction Type Lab Report

Here is a Reaction Type Lab Report, showing how displacements and combustion happen.

Reaction Type Lab

 
Purpose: The purpose of this experiment is to carry out the reactions using your knowledge of reaction types.

 
Materials:

6 test tubes

Iron (Fe)

Hydrochloric acid (HCl)

Copper(II) sulfate (CuSO4)

Zinc (Zn)

Lead(II) Nitrate [Pb(NO3)2]

Sodium hydroxide (NaOH)

potassium iodide (KI)

 

Procedure:

After we gathered all of our materials, we needed to carry out a metal with an acid. We choose HCl (Hydrochloric acid) and Fe (iron). We choose HCl because it was the only acid, and we needed a metal, so we decided to use iron. We waited to see what chemical changes occurred then recorded them. For the 2 single replacements we needed to carry out, the first one, we choose Zn (Zinc) and CuSO4 (Copper Sulfate). We knew that there would probably be a chemical change because since it is a single replacement, Zinc needed to be more reactive than Copper, and after we looked on the activity series sheet, we knew Zinc was more reactive. We waited to see what chemical changes occurred then recorded them. For the second single replacement, we choose Zn (Zinc) and Pb(NO3)2  [lead (II) nitrate]. Because we needed a single replacement, zinc was more reactive than lead according to the activity series, so we knew a chemical change should of occurred. We waited to see what chemical changes occurred then recorded them. We also needed to carry out 3 double replacement reactions that formed precipitates. For the first double replacement reaction, we used CuSO4 (copper sulfate) and NaOH (sodium hydroxide). We waited to see what chemical changes occurred then recorded them. For the second double replacement we  needed to carry out, we choose Pb(NO3)2 [lead (II) nitrate] and KI (potassium iodide). We waited to see what chemical changes occurred then recorded them. For the third double replacement, we choose KI (potassium iodide) and Copper(II) sulfate (CuSO4). We waited to see what chemical changes occurred then recorded them. We used the solubility rules to help us figure out which compounds of the products would form precipitates, and which of them would be soluble and dissolve in water.

 
Results:

 Fe(s) + 2HCl (aq)  —> FeCl2 (aq)+ H2(g)               
Formation of a gas

CuSO4 (aq) + Zn(s) —>  ZnSO4(aq) + Cu(s)   
Formation of a solid on the zinc metal, formation of a gas, corroding of metal

 Zn(s) + Pb(NO3)2(aq)  —>  Zn(NO3)2(aq) + Pb(s)
Formation of a solid

 CuSO4(aq)+ 2NaOH(aq) —> Cu(OH)2(s) + Na2SO4(aq)
Blue jell formed  and floated in the blue liquid, formation of a precipitate

 Pb(NO3)2(aq) + 2KI(aq) —> PbI2(s) + 2KNO3(aq)
Bright yellow liquid, yellow solid formed on bottom, color change and a formation of a solid

CuSO4 (aq) + 2KI(aq) —> CuI2(s) + K2SO4(aq)       
Layers of yellow, green and blue, color change

    in this web I found the reaction between CuSO4+KI=?

    A sugestion:

    add more chemical reactions like this

    I did the reaction between CuSO4 and KI at school at got a grey brown precipitate and a ‘Iodine’ coloured liquid. My source also stated that there would be solid iodine
