What chemical reaction is Zinc undergoing in a alkaline battery?
In an alkaline battery zinc is giving up electrons, so it's being reduced.
What is in a AAA alkaline battery?
An AAA alkaline battery typically contains a zinc anode, manganese dioxide cathode, and potassium hydroxide electrolyte. These components work together to generate electricity by a chemical reaction within the battery.
Why does an Alkaline battery last longer than an acid dry battery?
Alkaline dry cells last longer because NH4Cl, an acid found in non-alkaline, is replaced with KOH or NaOH, a base found in alkaline. The Zinc in an alkaline dry cell batteries tends to corrode less in basic conditions.
What metal is used in a flashlight battery?
The metal used in a flashlight battery is typically zinc. Zinc-carbon batteries and alkaline batteries are common types of batteries used in flashlights, both of which contain zinc as a key component in their construction.
What is an alkaline battery?
The "non-alkaline" battery is probably best "defined" by comparing it to the alkaline battery. Both are chemical cells, but the alkaline battery has as an electrolyte a basic solution of potassium hydroxide. (A base is often said to be "alkaline" in chemistry.) The "non-alkaline" battery uses zinc and ammonium chloride, which are acidic, as an electrolyte. The alkaline battery packs a higher chemical energy density than the "regular" or, as it is marketed, "heavy duty" or "industrial" battery. That's why it is generally more expensive and lasts longer.

What element is in center electron post of a battery?
We find carbon or graphite as the center electrode of a zinc-carbon battery. It's the "common" battery we use in lots of stuff (but not an alkaline battery). That center electrode is the positive one, and the zinc makes up the outer or negative electrode in this battery. In an alkaline battery, manganese dioxide is the center, or the cathode (positive electrode). Powdered zinc will be found as the outer or negative electrode (anode).

What are batteries recycled into?
1. Carbon zinc Battery 2. Alkaline Battery 3. Mercury Battery 4. Lithium Battery
How many electrodes does a alkaline battery contain?
The two electrodes of the alkaline battery are zinc and manganese dioxide. Zinc is the anode, or the electrode that becomes negatively charged due to the electrolyte. Manganese dioxide is the cathode, or the electrode that becomes positively charged.
What metal is oxidized in the most common dry cell?
In the most common dry cell, which is the alkaline battery, zinc is the metal that is oxidized. When the battery is in use, the zinc undergoes oxidation at the anode, releasing electrons and generating electrical energy.
What is the difference between a 357 button battery and a 675 Button battery?
The 357 is an alkaline battery. The 675 is a hearing aid zinc battery and is far smaller than the 357. They are not interchangeable.
What is the difference between alkaline zinc plating and cyanide zinc plating?
The main difference between alkaline zinc plating and cyanide zinc plating is the type of bath used in the plating process. Alkaline zinc plating uses an alkaline electrolyte solution, while cyanide zinc plating uses a cyanide-based electrolyte solution. Alkaline zinc plating is considered more environmentally friendly compared to cyanide zinc plating, which contains toxic cyanide compounds.
Why is it possible for alkaline batteries to be smaller than zinc-carbon dry cells?
A battery can actually be made into any size, but very small batteries would be drained in a matter of seconds and are thus useless. Since zinc-carbon batteries contain less electrical energy per volume compared to an alkaline battery they are normally used for the larger sizes of batteries. Rayovac has published a graph where the zinc-carbon and alkaline batteries have been compared. It shows that the alkaline battery works just as good after 17 hours of use as the zinc-carbon battery does after only 8 hours of use. (http://www.rayovac.com/technical/pdfs/pg_battery.pdf) Eurobatt claims that alkaline batteries can have 4-15 times longer lifetime than the zinc-carbon type. But it isn't mentioned under what type of conditions this is. (http://www.eurobatt.net/index7201.html?page=213&l=1)
