A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...

Sodium aluminate is manufactured by the dissolution of aluminium hydroxide (Al(OH) 3) in a caustic soda (NaOH) solution. Aluminium hydroxide can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point. The use of more concentrated NaOH solutions leads to a semi-solid product.
The density of the solution is 1.093 g ... combined with sodium hydroxide at about or below 25 °C. ... to common container materials such as stainless steel [8] ...
or also by neutralizing it with sodium hydroxide (however, this reaction is very exothermic): HNO 3 + NaOH → NaNO 3 + H 2 O. or by mixing stoichiometric amounts of ammonium nitrate and sodium hydroxide, sodium bicarbonate or sodium carbonate: NH 4 NO 3 + NaOH → NaNO 3 + NH 4 OH NH 4 NO 3 + NaHCO 3 → NaNO 3 + NH 4 HCO 3 2NH 4 NO 3 + Na 2 ...
