What is the difference between koh and naoh




















Potassium Hydroxide. For the kitchen exhaust cleaning contractor, almost any cleaner you would want to use on the market today will be based on one or the other of these chemicals, or be a combination of the two. You need to understand their differences, pros and cons, to be able to best choose a product to fit your needs.

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 are 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 possess.

But to get a better understanding of when to choose one over the other, you need to understand the similarities and differences between potassium hydroxide and sodium hydroxide. Potassium hydroxide and sodium hydroxide are both highly corrosive, strong bases. Both are formed by ionically binding an alkali metal to a hydroxide group.

Of all the compounds in the hydroxide group, potassium hydroxide and sodium hydroxide are the most chemically similar. Their strong chemical similarity allows them to easily stand in for each other in a number of uses. Accordingly, their chemical reactions are remarkably similar. Because potassium hydroxide and sodium hydroxide are both strong bases, they react to water by releasing heat. So they are both highly exothermic.

Their chemical similarity lends to a physical similarity as well. In solid form, they are both white powder or flakes. When dissolved they can each be used as an aqueous solution. Though sodium hydroxide and potassium hydroxide are very similar, they are fundamentally different.

To begin with, potassium and sodium each contribute a different number of protons. Sodium brings in 11 protons, while potassium donates Likewise, the metal in sodium hydroxide is lighter than that of potassium hydroxide. The flakes bubble and rattle at the bottom of the mixing container. Due to the corrosiveness of the chemical compounds, it is important, as with any lye solution, to be sure that you are wearing proper safety gear such as gloves, goggles, and long sleeves.

For the sake of safety, it is important to concentrate entirely on the soapmaking process, distraction-free from children, pets, spouses, and phones.
