KOH is potassium hydroxide, an Arrhenius base. All ionic compounds are soluble (they ionize in the polar water). This particular ionic compound also has all these loose hydroxide anions in solution, making it a base. never drink, or stick your finger in it, it burns like heck! looks like water, tastes like death.

Many hydroxides are insoluble in water, such as metal hydroxides like copper(II) hydroxide. However, alkali metal hydroxides like sodium hydroxide and potassium hydroxide are soluble in water.
Yes, sucrose is soluble in sodium hydroxide. When mixed with sodium hydroxide in water, sucrose will dissolve to form a clear solution.
Among common metal hydroxides, potassium hydroxide (KOH) is the most soluble in water.
Most hydroxide compounds are soluble in water. However, the solubility can vary depending on the specific hydroxide compound. Common hydroxide compounds like sodium hydroxide (NaOH) and potassium hydroxide (KOH) are highly soluble in water.
Sodium oxide is soluble in water and will react with water to form sodium hydroxide. The resulting solution will be basic because of the presence of sodium hydroxide.
Iron III oxide is not soluble in sodium hydroxide. Iron III oxide is an insoluble compound that does not dissociate into ions in water.
