The Truth Behind Calcium Hydroxide Usage

Calcium hydroxide is one of the chemical compounds that are not associated in calcium supplement manufacturing because of the presence of acidic properties. It takes the form of either white powder or colorless crystal which is produced when another chemical compound which is the calcium oxide is quenched with water. It can also be produced by the mixture of the aqueous (water-based) solution of sodium hydroxide and the aqueous solution of calcium chloride.

When processed under heat, it decomposes into water and calcium oxide. One of the products, which is the lime water (formed by a suspension of fine particles of calcium hydroxide in water) is considered to be a medium-strength base which reacts viciously with acids as well as assails many metals in the presence of water.

Due to its sturdy basic properties, calcium hydroxide is used on various applications, such as the following:

When in the form of lime, it is used as a sewage treatment and for the improvement of acid soils.

It is an active ingredient in the production of plaster, whitewash, and mortar.

It also acts as an alkaline which is used as a non-lye substitute in lye-free hair relaxers.

It is also used as a reagent in the following applications:

For the reef aquarium as a bio-available calcium additive solution for organisms inside the aquarium that uses calcium such as snails, algae, corals, and hard tube worms.

For the tanning industry as a neutralizer on extra acids.

For the petroleum refining application as an ingredient for manufacturing oil additives such as sulphatic and fanatic.

For the chemical application as an ingredient in manufacturing calcium stearate.

For water processing such as alcoholic and soda drinks.

For clearing magnesium and carbonate contents of calcium in manufacturing salt for food.

It is also used as a filler on the following applications:

Solid oil manufacturing.
Brake pad manufacturing.
Ebonite production.
Dry mix preparation for decorating and painting.
Pesticide mix manufacturing.
Polikar manufacturing (a drug that is used as a preservative for vegetables and fruits during storage period).

It is also used in paste which is employed in tooths root canal procedure which reduces inflammation as well as acting as a disinfectant within the infected area.

However, since it contains acidic properties, calcium hydroxide overdose can lead to dangerous consequences such as breathing difficulties, internal bleeding, hypotension, skeletal muscle paralysis, and an increase in the bloods pH level, which can cause damage to the bodys internal organs.

Calcium Carbide The Illuminating Chemical Compound

Just like with other calcium compounds that contains the suffix ide in their names, calcium carbide is not also associated in the production of calcium-based supplements. It is commonly used on modern industrial applications as well. Read on the preceding contents of this article and learn more about calcium carbide.

Chemical Compound Reaction

Bearing the chemical formula CaC2, calcium carbide is produced through the process of electrostatic discharge by means of mixing carbon and lime at high temperature. When reacted with water, it produces acetylene. Such reaction is the principle behind the production of dissolved acetylene which is the only modern industrial use of calcium carbide.

Application

The most common application of calcium carbide is on so-called carbide lamps (also known as acetylene lamps) wherein it uses acetylene gas which is produced by means of combining the chemical compound and water. Such lamps were formerly used in mines.

Calcium carbide in this application takes the form of small pellets or chunks that is placed on the lower chamber of the lamp. Its upper chamber is filled with another reactant, which is water. There is a screw valve or similar mechanism which controls the drip rate of water to the lower chamber where the calcium carbide is stored. Such water drip rate control results to the production of acetylene gas. It results in control of the size of the flame as well as the quantity of light that it produces.

The reaction of water with calcium carbide generates enough quantity of heat apart from the flame. In cold cave conditions, the heat can be used to save someone from hypothermia.

After the entire quantity of calcium carbide is reacted with water, the lower chamber contains now a wet paste of calcium hydroxide or caustic lime which is emptied in order to be refilled for the next usage. The caustic lime is toxic on humans and animals and must be deposited on a place wherein no one will be affected.

The next application of calcium carbide is the flare which is a type of pyrotechnic that emits a brilliant light as well as intense heat without the occurrence of an explosion. It is commonly used as a signal and illumination (especially on small fishing boats) as well as defensive counter measures in military and civilian applications.

Calcium carbide is only handled within industrial production. Individuals who work with this chemical compound always take some precautionary measures to avoid any untoward incident that may happen due to mishandling of calcium carbide.
