based on 1 rating
By — McGraw-Hill Professional
Updated on Feb 8, 2011

For a quick review on stoichiometry, refer to the following concepts:

Synopsis

Solutions containing various ions are tested for the presence of certain specified ions. The formation of colors, gases, or precipitates indicates the presence or absence of certain ions. (See the Reactions and Periodicity chapter.)

Equipment

      beaker(s)
      centrifuge
      evaporating dish
      funnel
      mortar and pestle
      Pt or Ni test wire

Measurements

This is primarily an observation experiment. No precise measurements are needed.

Calculations

No calculations are required.

Comments

A wide variety of cations or anions may be used. Many of the results are a simple application of the solubility rules.
