- Draw a picture representing a molecular-level view of the two solutions used in Reaction A before mixing and a picture of the solution that results after they are mixed. (3 pictures total)
+
Pb(NO3)2 (aq) KI (aq) mixture after the
reaction
Data Table 1:
|
Reaction |
Observations |
|
A: Pb(NO3)2 + KI |
Powdery appearance, stuck to the walls of the test tube, solution has a yellow color |
|
B/C: NiCl2 + AgNO3 |
Powdery white, percipate accumalted as pellets at the bottom |
|
D: H2SO4 + Indicator |
Yellow color when indicator added |
|
E: NaOH + Indicator |
Dark blue when indicator is added |
|
F: H2SO4 + NaOH |
Yellow with 10 drops, then after the 23rd drop turned blue |
|
G: Na2CO3 + H2SO4 |
After 20 drops Na2CO3 dissolved, after two drops of indicator it turns a dark blue after 20 drops of H2SO4 a gas is produced and changes to yellow, adding more sulfuric acid didn’t produce more bubbles |
|
H: Mg + H2SO4 |
Solid magnesium strip no longer visible |

I am having trouble creating a procedure to use to identify five
unknown solutions we will be given in chem lab.
The five solutions will be an acid, a base, a chloride salt, a
nitrate salt, and a sodium salt. I have to come up with steps to
determine which compound is in each category. Only one will be in
each solution.
Acid- HCl, HNO3, H2SO4
Base - NaOH, NH3, Na2S
Chloride Salt - NaCl, BaCl2, CuCl
Nitrate Salt -...

Why does the infinity reaction not require an infinite amount of
time?
PROCEDURE:
Prepare 60 mL of a 1:1 (by volume) solution of distilled water
and 2-propanol in a beaker. Be as precise as possible. After mixing
well, wait 10-15 minutes to allow the contents to come to room
temperature as some heat will evolve during the mixing of the two
liquids.

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean,
dry, glass centrifuge tube. 2. Place a piece of copper wire in a
weighing paper, determine the mass of the wire and place it in the
centrifuge tube. The copper wire should weigh less than 0.0200
grams. 3. In a fume hood, add seven drops of concentrated nitric
acid to the reaction tube so that the copper metal dissolves
completely. Describe your observations in the lab report. (Caution,

Making Heat with Chemical Reactions
Have you ever wondered how an instant heat pack works? A
disposable heat pack works by a chemical reaction that combines
iron in the package with oxygen from the air when the outer
packaging is removed producing iron oxide. You have probably seen
the product of this reaction in what is commonly called rust. The
reaction releases heat, which allows the pack to reach a sufficient
temperature that is...
