    This document describes a flame test lab activity where students will determine the characteristic colors that metal salts emit when burned. Students will place small amounts of calcium chloride, sodium chloride, potassium chloride, and copper(II) sulfate on watch glasses, add acid and alcohol, and observe the color of the flame when lit with a match. The colors produced can be used to identify the metal elements present based on the structure of their atoms. Students are asked questions about why different colors are emitted and what particles are responsible for producing the colored light.

    Activity 1.2.1
    The Flame Test

    Name: __________________________________________ Date: ___________________


    Section: ________________________________________ Teacher: _______________________

    I. OBJECTIVE:
     Determine the characteristic colors that metal salts emit; and
     Relate the colors emitted by metal salts to the structure of the atom.

    II. MATERIALS:
    0.50 grams of each of the following metal salts:
    Calcium chloride 6 pcs watch glass
    Sodium chloride 1 pc 10 mL graduated cylinder
    Copper(II) sulfate 1 pc dropper
    Potassium chloride safety match
    100 mL 95% ethanol
    100 mL Hydrochloric acid

    III. PROCEDURE:
    1. Place each metal salt on a watch glass and add 2 to 3 drops of 3 M hydrochloric acid.
    2. Pour about 3-5 mL or enough alcohol to cover the size of a 1-peso coin in the first watch glass. Light a
    match and observe the color of the flame.
    3. Repeat procedure No. 2 for each salt. Observe the color of the flame.
    4. Write your observation in the table below.

    Table 1: Color of the flame of metal salts


    Metal salt tested Element Producing Color Color of the flame
    Calcium Chloride Boron
    Sodium Chloride Calcium
    Potassium Chloride Sodium
    Copper(II) sulfate Potassium
    Boric Acid Copper

    Questions:
    1. Why do you think there are different colors emitted?
    2. What particles in the heated compounds are responsible for the production of the colored light?
    3. How did the scientist explain the relationship between the colors observed and the structure of the
    atom?
