Caustic (sodium hydroxide) is added to water to increase the pH levels and neutralize acidity. This helps in water treatment processes by enhancing the coagulation and flocculation of particles, aiding in disinfection, and preventing corrosion in pipes and equipment.
To raise the pH of water to 7 using 25% caustic soda (sodium hydroxide), you need to determine the current pH of the water. Without knowing the initial pH, it's difficult to calculate the exact amount needed. Generally, small increments should be added, and pH should be tested frequently. A typical starting point might be to add about 1-2 ounces of 25% caustic soda, mix thoroughly, and then measure the pH before adding more, since caustic soda is very strong and can quickly raise the pH.

This is just a guess, but if I saw that in an archaic formulary I'd probably assume they were talking about aqueous sodium hydroxide. "Liquor" is sometimes used in chemistry as a general term meaning solution, and "caustic soda" is an old term for sodium hydroxide.
The white stuff formed at the bottom when caustic soda is mixed with water is typically sodium hydroxide crystals. These crystals result from the exothermic reaction that occurs when caustic soda dissolves in water, causing the solution to heat up and potentially precipitate solid sodium hydroxide.

No, vinegar should not be used to neutralize caustic soda on the skin. It can actually react with the caustic soda and worsen the burn. Rinse the affected area with plenty of water and seek medical attention immediately.
Caustic soda, also known as sodium hydroxide, is denser than water. Its density is around 2.13 g/cm³, which means it sinks in water.

Caustic potash is potassium hydroxide (KOH), while caustic soda is sodium hydroxide (NaOH). Both are strong alkaline compounds used in industrial processes such as chemical manufacturing and water treatment, but they differ in their chemical composition and properties.
Adding caustic soda (sodium hydroxide) to water raises the pH because it is a strong base that increases the concentration of hydroxide ions in the solution, making it more alkaline.
