Cabbage Juice Titration Lab
Introduction: Red cabbage juice is an example of an acidbase
indicator. In chemistry, an indicator is used to detect the presence of a
specific chemical or a specic type of chemical. In this lab, r
4. Transfer the fluid into a glass or jar, pouring it through a strainer
to remove the cabbage pieces.
Using cabbage juice as an indicator during titration:
1. First you need to calibrate your eyedropper.
2. Figure out how many
If it looks like the water solution created in procedure 5, you
have added too much NaHCO3.
Record the total number of drops of the sodium bicarbonate
solution you added to the vinegar in the Data Table.
1. Write the balanced equation for the reaction of acetic acid
(CH3COOH) and sodium bicarbonate (NaHCO3). What type of
reaction(s) took place?
2. Calculate the number of moles of NaHCO3 that were required to

Chromatography: Separating Mixtures
Magic marker inks are often mixtures of several compounds. Paper chromatography
is a common method of separating various components of a mixture. After
separation, you can observe the different colors that
Stoichiometry can be thought of as the math of chemistry. It involves using
relationships between reactants and/or products to determine such quantities as
mass, moles, and number of atoms. Dimensional analysis is a way
Researching Elements in the Periodic Table:
The periodic table includes groups of elements that have unique and useful capabilities.
Such capabilities are due to the properties of the elementssuch as ionization energy,
Six basic nutrients and their functions:
1. Carbohydrates are sugars thats are complex. Carbohydrates consist of starch and dietary fiber.
They are used first to fuel muscles and the brain.
You can represent a molecule two-dimensionally, as a structural formula or electron dot structure.
Although such models are useful in certain contexts, they do not accurately
