Manganese(II) chloride is the dichloride salt of manganese, MnCl 2.This inorganic chemical exists in the anhydrous form, as well as the dihydrate (MnCl 2 ·2H 2 O) and tetrahydrate MnCl 2 ·4H 2 O), with the tetrahydrate being the most common form. Like many Mn(II) species, these salts are pink, with the paleness of the color being characteristic of transition metal complexes with high spin d ...

Manganese dioxide is used to: manufacture ferroalloys; manufacture dry cell batteries (it's a depolarizer); to "decolorize" glass; to prepare some chemicals, like oxygen and chlorine; and to dry black paints. Manganese sulfate (MnSO 4) is used as a chemical intermediate and as a micronutrient in animal feeds and plant fertilizers.

Note that the battery in this tutorial is a zinc-carbon dry cell. This tutorial does not cover the dismantling of an alkaline-type cell. Alkaline cells are of slightly different internal construction and contain the strong base potassium hydroxide as an electrolyte, which is rather more dangerous to handle than the ammonium chloride/zinc chloride mixture used in zinc carbon cells.

The use of manganese compounds stretches back more than 17,000 years. Ancient cave paintings, including those in Lascaux France, derive their color from manganese dioxide. Manganese metal, however, was not isolated until 1774 by Johan Gottlieb Gahn, three years after his colleague Carl Wilhelm Scheele had identified it as a unique element.

Made with manganese dioxide and zinc as prime materials, the carbon-zinc, battery is one of the most widely used batteries. When a voltage drop begins after hours of use, you can continue using the battery at a satisfactory level of performance by letting it operate and rest at intervals.

Manganese is mainly used in metallurgical processes, as a deoxidizing and desulfurizing additive and as an alloying constituent. It is also used in the production of dry-cell batteries, in chemical manufacturing, in the manufacture of glass, in the leather and textile industries, and as a fertilizer.

Manganese(IV) oxide was used in the original type of dry cell battery as an electron acceptor from zinc, and is the blackish material in carbon–zinc type flashlight cells. The manganese dioxide is reduced to the manganese oxide-hydroxide MnO(OH) during discharging, preventing the formation of hydrogen at the anode of the battery.

Other types of batteries include a lithium/manganese dioxide battery, which has a flat discharge characteristic—it provides approximately the same amount of power at the beginning of its life as at the end—and can be used where there is a need for small, high-power batteries (smoke alarms, cameras, memory backups on computers, and so on).

The thin metal used in making aluminium beverage cans contains about 1% Mn to prevent metal corrosion. Manganese in dry-cell batteries helps to reduce production of waste matter. The generation of electricity causes hydrogen gas to accumulate on battery electrodes. MnO 2 acts as a depolarizing agent, reacting with the

This tutorial shows how to take apart a spent zinc-carbon dry cell of the common type. Besides making for an interesting object lesson in electrochemistry, taking apart a spent D-cell, for instance, allows you to salvage many materials which can be of use to amateur chemists–materials which would otherwise probably end up in a landfill.

An alkaline battery (IEC code: L) is a type of primary battery which derives its energy from the reaction between zinc metal and manganese dioxide.. Compared with zinc-carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have a higher energy density and longer shelf life, yet provide the same voltage.. The alkaline battery gets its name because it has an alkaline ...

Dry cells are typically used as primary cells, and these batteries can handle long periods of storage because they lose their charge more slowly than secondary batteries. Lithium ion batteries represent a type of dry cell battery well-suited for use in cell phones, due to its high energy density, or its power stored versus weight.
