What is ICE Box?

I missed the lecture on "Ice Box", but this is what I've learned so far. ICE stands for Initial Change Equilibrium. It's also easier for me to learn through visuals and example, so I mostly just have links of pictures to share. http://chemwiki.ucdavis.edu/Core/Physical_Chemistry/Equilibria/Le_Chatelier's_Principle/Ice_Tables

ACID BASE

For acid base reactions, it's important to know how to determine pH and pOH of solutions. Basically, you're just finding the H+ or OH- concentration of the solution.

EX: 

The pH of a 12.5 M solution of HCl

pH= -log [H+]

-log [12.5 M]

pH= -1.097

Titration Lab

Today, we did an acid base lab. We put an NaOH solution into a buret, and we titrated until you could no longer see the pink color (from the Phenolphthalein indicator) in the KHP solution, and then did the same with a vinegar.

ACIDS: taste sour and feel sticky

BASES: taste bitter and feel slippery

ARRHENIUS ACIDS AND BASES

-Arrhenius acids are those species that produce hydrogen ions in solution (H+)

-Arrhenius bases are those species that produce hydroxide ions in solution (OH-)

HCl-->H+ + Cl-    (strong acid)

NaOH-->Na+ + OH- (strong base)

WATER CAN BE AN ACID OR A BASE (amphoteric)

BRØNSTED-LOWREY ACIDS AND BASES

Brønstead-Lowery acids donate a proton (H+)

Brønstead-Lowery bases accept a proton (H+)

HCl + H2O --> H3O+ + Cl-

Acid-Conjugate Base Pair [HCl and Cl-]

Base-Conjugate Acid Pair [H2O and H3O]

EX: HClO4 and ClO4- because H+ + ClO4-

Juice Lab

Testing for Vitamin C Content In Beverages

TITRATION

For the lab, we placed 20 drops of juice (V8 Golden Goddess, Pear Nectar, Apple, Unsweet White Grapefruit, and a Standard Vitamin C Solution) into a test tube, along with 3 drops of starch. We added I2 drop by drop until the color of the solution changed to blue. We then recorded the number of drops it took to turn the solution blue.
