What is the total reduction potential of a cell in which lithium (Li) is reduced and mercury (Hg) is oxidized?
-3.90v
Apex sucks!!
What else can I help you with?
How is zinc used in the reduction of mercury?
Zinc is used in the reduction of mercury by forming an amalgam with mercury, which allows the mercury to be easily separated from other materials. This process helps to extract and purify mercury from its ores.
Can mercury dissolve in hydrochloric acid?
No. A metal will "dissolve" in acid if it ionizes (going from a neutral metal atom to a cation)... therefore this is an oxidation-reduction problem! Since mercury goes from neutral to cation (positively charged ion), that means it loses electrons, or is oxidized. That means something else needs to be reduced (or gains electrons). In an HCl solution, you have lots of H+ and Cl-. Only H+ can gain electrons, since Cl- is already an anion (negatively charged ion). If you look at a table of standard reduction potentials, you see that 2H+ + 2e- => H2 E=0V 2Hg => Hg22+ + 2e- E=-0.80V Therefore, the total reaction 2H+ + 2Hg => H2 + Hg22+ has a potential E=-0.80V, meaning this reaction is not spontaneous (since E<0V). In real life, adding mercury to HCl (no matter how concentrated) will just result in the mercury sinking to the bottom of the container. Hope this helps.
What is the role of mercury in clemmensen's reduction?
In Clemmensen reduction, mercury acts as a catalyst to promote the reduction of carbonyl compounds (such as ketones or aldehydes) to alkanes. It forms a complex with the carbonyl compound, facilitating the transfer of hydrogen atoms from zinc amalgam to the carbon-oxygen bond, leading to the formation of an alkane product.
Can you mix mercury with sulfuric acid?
It is not recommended to mix mercury with sulfuric acid as it can create toxic mercury vapor. This reaction can be dangerous and should be avoided due to the potential health risks associated with exposure to mercury vapor.
In what state of matter is lithium naturally?
Lithium is a solid at room temperature. It turns into a liquid at 453.69 K, and boils at 1615 K.
What products are produced when lithium reacts with mercury?
A lithium amalgam is formed.
What is oxidized Mercury?
Oxidized mercury refers to mercury that has combined with oxygen to form mercury oxide compounds. This can occur through chemical reactions or exposure to air and moisture.oxidized Mercury is less toxic than elemental mercury, but some mercury oxide compounds can still pose health hazards.
How is zinc used in the reduction of mercury?
Zinc is used in the reduction of mercury by forming an amalgam with mercury, which allows the mercury to be easily separated from other materials. This process helps to extract and purify mercury from its ores.
What will be true if mercury and zinc are used to form an electrochemical cell?
A.Mercury will be reduced.B.Liquid mercury will form.E.Zinc will be oxidized.

Why does the mercury go down when its cold?
When it's cold, the molecules in the mercury slow down and become more compact, leading to a decrease in volume. This reduction in volume results in the mercury level dropping in a thermometer.
Which batteries are used in medical apparatus?
Zinc-mercury oxide battery - often used in hearing-aids. Lithium-iodide battery - Lithium-iodide chemistry is used in pacemakers and hearing aides because of their long life.
Name a metal on the peridoic table?
Tungsten. Mercury. Tin. Gold. Lithium. Potassium. Calcium. Sodium. Titanium. Chromium.....................................................
Is mercury an alkali metal?
No, mercury is not an alkali metal. It is a transition metal that is located in group 12 of the periodic table. Alkali metals are the elements in group 1 of the periodic table, such as lithium, sodium, and potassium.
