Question

State 5 differences between Caustic soda and Caustic potash.​

Answer 1

Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH) are almost interchangeable. They are the most chemically similar of the hydroxides. They are both a white, strong alkaline, corrosive solid or powder. Sodium Hydroxide is more commonly known as lye or caustic soda where Potassium Hydroxide is known as potash.

Both are used to change fats into soap in a process called saponification. Even though their solubility in room temperature water is about the same, products made with potassium hydroxide exhibit a greater solubility, especially as you increase the temperature of the water. Like all strong bases, the reaction of both Potassium Hydroxide and Sodium Hydroxide with water is strongly exothermic; in other words, they generate heat and give off hydrogen. But the reaction with Sodium Hydroxide is slightly more exothermic, which can make up for other more positive factors that Potassium Hydroxide possesses.

The biggest difference between them is in cost because of certain factors, such as their production process by electrolysis, where potassium chloride costs more than sodium chloride (table salt). In ton quantities, potassium hydroxide is about three times more expensive than sodium hydroxide.¹
At the molecular level, potassium hydroxide is also slightly smaller than sodium hydroxide; therefore, it can penetrate oil molecules faster than sodium hydroxide, thus breaking the oil’s hold on surfaces quicker. Since they are also more soluble, the oils can be rinsed away easier, especially when using hotter water or steam equipment.
