What gets oxidized in a galvanic cell made with magnesium and zinc electrodes?
ankoles [38]

Answer: Magnesium

Explanation:

Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.

The standard reduction potential for magnesium and zinc are as follows:

E^0_{[Mg^{2+}/Mg]}= -2.37V

E^0_{[Zn^{2+}/Zn]}=-0.76V

Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).

Here Mg undergoes oxidation by loss of electrons, thus act as anode. Zinc undergoes reduction by gain of electrons and thus act as cathode.

Mg\rightarrow Mg^{2+}+2e^-

Zn^{2+}+2e^-\rightarrow Zn

Thus magnesium gets oxidized.

Before the battery in the car is jumped, the individuals notice the hook-ups on the battery are corroded by acid. what substance
Vilka [71]

Answer:

Baking soda

Explanation:

Due to its neutralizing properties, sodium bicarbonate can be used to counteract the acid corrosion of car batteries. To use baking soda, in this case, be sure to disconnect the battery terminals before cleaning. Make a paste of three parts baking soda to one part water and apply with a damp cloth to rub the corrosion of the battery terminal. After cleaning and reconnecting the terminals, clean them with petroleum jelly to prevent future corrosion.
