Sodium hydroxide is also called as sodium hydrate, caustic soda or lye. This is a white solid. It is available in flakes, pellets, granules and a 50% saturated solution. As it absorbs carbon dioxide from the air, it has to be stored in an airtight container. It can be dissolved in water accompanied by liberation of heat. It can also be dissolved in ethanol, methanol and potassium hydroxide.
Manufacturing of Sodium hydroxide
The following methods are used:
Membrane cell process
There exists a Nafion membrane to separate the cathode and anode reactions. Across this membrane, only sodium ions and a small quantity of water pass through it. A very standard quality of NaOH is produced. A very low consumption of electric energy is needed and the quantity of steam required for concentration of the caustic is very less.
Diaphragm cell process
A steel cathode is used. The reaction of caustic soda with chlorine is prevented using a porous diaphragm. This is often made of asbestos fibers. During this process, the anode area is separated from the cathode area using a permeable diaphragm. Brine is input into the anode compartment and this flows across the diaphragm into the cathode compartment. Caustic brine in a diluted condition leaves the cell. This has to be concentrated to 50% and the salt has to be removed. An evaporative process is used where there are three tonnes of steam per tonne of caustic soda. This salt is separated from the caustic brine and is used to saturate dilute brine. The chlorine is purified by liquefaction and evaporation.
Mercury cell process
Sodium ions are reduced to sodium metal. This forms an amalgam with a Mercury cathode. This then reacts with water to form NaOH. Although, mercury releases are harmful, modern plants are good in this respect.
Characteristics of Caustic soda
Gastrointestinal symptoms include:
A sodium hydroxide solutin is some amount of sodium hydroxide (NaOH) dissolved in pure water (H2O), written NaOH(aq) or Na+(aq) + OH-(aq) (where aq is the state symbol for aqueous meaning in solution in water). The amount of NaOH in your solution is given by the molarity (M) of that solution, which is equal to the number of moles of NaOH divided by the total volume of the solution.
The function of sodium hydroxide solution is absorb carbon dioxide.
Since NaOH is a strong base, shouldn't it be pOH=[NaOH]? Then pH=14-pOH?
Yes, it is easy possible to prepare a sodium hydroxide solution in water.
1 molar NaOH is pH 14
Sodium hydroxide is also known as lye.
A homogeneous solution of Na OH in water.
Similar to bleach?

Neutralization reaction occurs.
Ca(OH)2 is also known as slaked lime.
