1
New cards
Qualitative Analysis
A method of analysis that focuses on identifying ions in a solution rather than measuring their amounts.
2
New cards
Cation
A positively charged ion, which is the focus for identification in this experiment.
3
New cards
Precipitate
A solid that forms and settles out of a liquid mixture upon mixing two solutions.
4
New cards
Solubility Categories
Products formed in the experiment are categorized as soluble (S), slightly soluble (SS), or insoluble (I).
5
New cards
Balanced Molecular Equation
A chemical equation that shows the reactants and products in their correct proportions, without including charges.
6
New cards
Ionic Equation
An equation that shows all the ionic species present in a solution during a reaction.
7
New cards
Net Ionic Equation
An equation that shows only the particles that participate in a chemical reaction, excluding spectator ions.
8
New cards
Qualitative Observations
Observations made based on physical characteristics, such as color and form of a precipitate.
9
New cards
Double Replacement Reaction
A type of chemical reaction where two compounds exchange ions or form new compounds.
10
New cards
Spectator Ion
An ion that does not participate in the chemical reaction and is present in the solution throughout.
11
New cards
Electro Neutrality
The principle that compounds must have no net charge, meaning the total positive charge must balance the total negative charge.
12
New cards
Solubility Rules
Guidelines used to predict the solubility of ionic compounds in water.
13
New cards
Laboratory Safety
Practices followed to maintain safety in the laboratory, such as using fume hoods for hazardous materials.
14
New cards
Data Recording
The act of accurately noting observations and results according to established scientific protocols.
15
New cards
Analyzing Results
The process of comparing experimental findings with known information to identify unknown substances.
16
New cards

Soluble Salt (S)

The reaction mixture will be "water clear." The solution in the test tube may be colored, but there is no precipitate.

17
New cards

Slightly Soluble Salt (SS)

The reaction mixture will have some cloudiness but no obvious solid settling to the bottom of the test tube.

Note that a precipitate is any solid formed as the result of a chemical reaction. Thus, the cloudiness that is observed is indeed a (light) precipitate.

18
New cards

Insoluble Salt (I)

The reaction mixture will be an opaque mixture with solid settling to the bottom of the test tube.
