Lab Investigation #1
Why do liquids evaporate at different rates?
The evaporation of a volatile liquid is an endothermic process that results in a decrease of
temperature. The strength of intermolecular forces of attraction is relative to
How Could You Make More of This Dye?
A solution is a homogeneous mixture of two or more substances. The simple solutions
always contain one solvent and one or more solutes. With the solvent being the major liquid of
the mixture, most comm
What is the optimum mole ratio for a reaction?
When an equation is balanced, the moles of products that a given amount of reactants
will produce can be predicted. We use moles to count the number of molecules produced by
weighing the grams. When you predi
Lab Investigation #3
What is the identity of the unknown hydrate?
Compounds that contain water molecules as part of their crystal structure are
called hydrates. A hydrate is a pure substance because the water molecules
embedded in its cry
WHAT IS THE BEST WAY TO REMOVE SILVER ION FROM AN AQUEOUS
Chemical reactions can be noticed through color changes, solid formations, bubble formations or
temperature changes. Chemists use chemical reactions with chem
Titration of Vinegar
In this lab assignment we observed how to determine the molarity and
percent by mass of acetic acid in vinegar via titration, using 0.1M sodium
hydroxide as the titrant. Titration is when a basic solution of unknown
Kinetics Lab report
The rate of a reaction supposed to depend on the concentrations of reactants and possibly other
substances using rate law, which represents the dependence of the rate on concentrations. In the rate
law equation, Rate=k , where k
Electrochemistry: Which metals make the best battery?
Oxidation-reduction reactions are transfer of electrons that transfer from the reducing
agent to the oxidizing agent. When two half-reactions are separated, the electron flow occurs
Lab #3 Conclusion
Cobalt Complex Ions
After testing out the different combinations and placing them next to the controlled substances
(#1, #3 and #6), we noticed that when sodium chloride and copper chloride are mixed, it turns green.
