Physical & Chemical Properties
Substance: Mg (magnesium)
Color: Shiny silver
Odor: none
Effects of heat:
-In test tube 1 with just the Mg when heated nothing happened.
-In test tube 2 with the Mg mixed with water, when heated nothing happened.
-In test tube 3 with Mg mixed with HCL it started to sizzle and bubble.
-In test tube 4 with Mg mixed with NaOH it lost a little of its silver color and the solution turned a milky white color.
Solub. Or reaction w/cold H2O: No reaction or solub.
Solub. or reaction w/hot H2O: No reaction or solub.
Litmus test:
-Test tube 2 with water:
-Red- turned a little bluish
-Blue- turned a whitish color.
-Test tube 3 with HCL:
-Red- turned blue.
-Blue- turned pinkish purple
-Test tube 4 with NaOH:
-Red- turned blue.
-Blue- no change
Dilute HCL: Mg mixed with HCL it started to sizzle and bubble.
Dilute NaHO: Mg mixed with NaOH it lost a little of its silver color and the solution turned a milky white color.
Substance: Cu (copper)
Color: Shiny copper color
Odor: none
Effects of heat:
-In test tube 1 with just the Cu when heated nothing happened.
-In test tube 2 with the Cu mixed with water, when heated nothing happened.
-In test tube 3 with Cu mixed with HCL the solution turned a greenish color and the copper lost some of its shininess and lightened a bit in color.
-In test tube 4 with Cu mixed with NaOH the copper turned a dark color and a strange odor was produced.
Solub. Or reaction w/cold H2O: No reaction or solub.
Solub. or reaction w/hot H2O: No reaction or solub.
Litmus test:
-Test tube 2 with water:
-Red- turned a little bluish
-Blue- turned a redish
-Test
