1d) Write the net ionic equation. Include phases.

2a) Using a well plate, place a piece of Mg ribbon in a well and add 3 drops of 6 M HCl (aq).
• releases a gas; and gets hot

2d) Write the net ionic equation. Include phases.

3a) Using a well plate, mix together 3 drops of Pb(NO3)2(aq) and 3 drops of KI(aq).
• makes a yellow precipitate

4a) Using a well plate, mix together 3 drops of 0.10 M HCl(aq) and 3 drops of Ca(OH)2 (aq).
• nothing is seen because both products are clear solutions
b) Record your observations.

4c) Repeat this experiment except this time with 0.10 M HCl(aq) add 1 drop of phenolphthalein to the 0.10 M HCl(aq) and then add 3 drops of Ca(OH)2(aq).
• adding Ca(OH)2 to HCl with phenolpthalein turns pink.  Phenolphthalein is indicator that helps see the chemical reaction

4f) Write the net ionic equation. Include phases.

5a) Using a well plate, mix together 3 drops of distilled water and 1 drop of phenolphthalein to water and then add a small amount of calcium metal
• turns pink
