Electrolysis Test Study Guide QUESTIONS
AND ANSWERS
1. For an aqueous how does the H₂O (water) cut up up? - ANSWER-H2O --> H⁺, OH⁻
2. How do while to apply the electrochemical series? (FOR THIS TEST ONLY) -
ANSWER-(commonly it might be if there are extra than 2 elements in a compound
but for this take a look at)
3. When you notice (aq) it manner aqueous answer. Since aqueous answers means
dissolved in water, water is part to problems with (aq).
In an aq equation when you have
OH --> ?? - ANSWER-OH⁻ -e → O2(g) (abrieviated)
Full 4OH- -4e --> 2H2O + O2(g)
In the Electrochemical Series
4. For ________ ions (_ions), the higher up the electrochemical collection, the more easily
discharged. For _____ ions (_ions), the decrease down the electrochemical collection,
the extra effectively discharged. - ANSWER-Negative, Positive
KI(L) -->
NaBr(s) -->
LiCl(l) --> - ANSWER-KI(l) --> K(s) + I2(g)
NaBr(s) --> No Reaction
LiCl(l) --> Li(s) + Cl2(g)
5. Need to recognize - ANSWER-Electrodes can ONLY discharge 1 ion. Sometimes
there are greater than 1 ion at an electrode. In this case, the electrode discharges
the ion this is more conveniently discharged.
For negative ions (-ions), the better up the electrochemical collection, the more
without problems discharged. For fantastic ions (+ions), the decrease down the
electrochemical series, the extra conveniently discharged.
6. Show the stairs for this equation

8. What are the 8 uses of electrolysis? - ANSWER-Purification of metals
Electroplating
Chlorine production
Extraction of Hydrogen from water
Extraction of oxygen from water
Extraction of Reactive metals
Hair elimination
