Equilibrium Lab

Today's class was spent doing a lab. The sheet is called An Analogy for an Equilibrium Reaction. The purpose of the lab was to help familiarize us with a system in equilibrium and how certain conditions effect that system. We were allowed to share data but everyone must hand in their own lab.

The experiment:
First we had to transfer water from one cylinder to another by using straws then record the change in volume in each cylinder. This was repeated for three transfers until the data remained the same. Once this happened we had to had an additional 5ml to ONE of the cylinders (A) then repeated until we reached the point where three transfers gave the same data.

For the data a chart is required to record the number of transfers, volume of cylinder A, and volume of cylinder B. Next we had to plot the data on graph paper and answer the questions that followed. I'm not sure if the due date was set yet.

Tomorrow's scribe will be rawra=).

Reminder: Test Tomorrow!!!

T O D A Y' S C L A S S!

  • Ms K. handed back our Neutralization problems worksheet that was due TUESDAY!
  • Discussed naming Acids and Bases.
  • Received handouts.
  • Went over the answers to the problems done in class.
A C I D S

Binary Acids: have 2 elements. For ex. HBr and HCl
Monoprotic Acids: have one hydrogen atom HCl
Diprotic Acids: have two hydrogen atoms H2SO4

Triprotic Acids: have three hydrogen atoms H3PO4

Oxyacids: have one hydrogen, one oxygen, and one other element

Naming Acids

* Hydrogen _____ide --> Hydro _____ic Acid
* Hydrogen _____ate --> __________ic Acid
* Hydrogen _____ite --> __________ous Acid
Examples:
*H + Cl --> Hydro chloric Acid
*H + SO4 --> Sulfuric Acid
*H + SO3 --> Sulfurous Acid

Naming Bases
Name of the positive ion + hydroxide(OH) on the end
Examples:
Mg(OH)2 Magnesium + hydroxide = Magnesium Hydroxide
NaOH Sodium + hydroxide = Sodium Hydroxide

H A N D O U T S
