Investigation: Developing an Activity Series for Metal Copper (II), Magnesium and Nickel
Tong Wu
Question:
“What is the effect of solution type and metal type on metal reactivity as measured by whether a chemical reaction has taken place? ”
Prediction:
*Using metal magnesium as an example illustration I. (Magnesium reacts with lead (II) nitrate) Mg + Pb(NO3)2 Pb + Mg(NO3)2 II. (Magnesium reacts with zinc nitrate) Mg + Zn(NO3)2 Zn + Mg(NO3)2 III. (Magnesium reacts with iron (III) nitrate) 3Mg + 2Fe(NO3)3 2Fe + 3Mg(NO3)2
Variables: The dependent variable for this investigation is the reactivity of each metal as measured by the occurring of chemical reactions between each combination of three solutions (0.1mol/L) and three metals. Recall that there are four common clues that indicate whether a chemical reaction has occurred. These include a change in colour of reactants, a formation of a precipitate, a given off of odour and a given off of heat/light.
The independent variables for this investigation are the types of solutions and the types of metals used. The three types of metals are Copper (II), Magnesium and Nickel and the three types of solutions being used for reactivity test are lead (II) nitrate (0.1mol/L) , zinc nitrate (0.1mol/L) and iron (III) nitrate (0.1mol/L). A total of nice trials are going to be carried out with different combinations of a metal and a solution. The combinations include copper (II) with lead (II) nitrate, copper (II) with zinc nitrate, copper (II) with iron (III) nitrate, magnesium with lead (II) nitrate, magnesium with zinc nitrate, magnesium with iron (III) nitrate, nickel with lead (II) nitrate, lead with zinc nitrate and lead with iron (III) nitrate.
The controlled variables for this investigation are the amount of each type of solution used for each trial, the time each metal strip being submerged into each solution and the temperature (cannot be controlled
