Question
When a piece of cadmium (Cd) is placed a solution of nickel chloride (NICI2), the following reaction occurs:
Cd (s)
+ NiCl2 (aq) - CdCl2 (aq) + Ni (s)
During this reaction cadmium (Cd) atoms are converted to Cd2+ ions while NI2+ ions are converted to nickel (Ni) atoms. Use the equation above to answer the following
questions.
1. Cadmium solid consists of neutral atoms. Give the number of protons and electrons in a cadmium atom.
protons
electrons
2. Cadmium atom is a
(neutral or charged) particle
3. CdCl2 contains Cd2+ ions. Give the number of protons and electrons in a Cd2+ ion
protons
electrons
4. Cadmium ion is a
(neutral or charged) particle
5. Cd atoms are
(losing or gaining ) two electrons in the reaction.
6. Cd atoms are being
(oxidized or reduced) in the reaction.
7. Ni2+ ions are
(losing or gaining) two electrons inthe reaction.
8. Ni2* ions are being
(oxidized or reduced) in the reaction.
9. According to the reaction above, Cd is a
(more or less) active metal than Ni.
10. Cadmium (Cd) would be located
(above or below) nickel (Ni) on the "activity series".
(Yes or No)
11. Would you expect a reaction to occur if a piece of nickel (Ni) is placed in a solution of cadmium(II) chloride (CdCI2)?
