Ionic Compounds and Their Properties

The video tutorial discusses whether potassium hydroxide (KOH) is an electrolyte or a non-electrolyte. It explains that KOH is an ionic compound, which dissolves in water to form ions, making it a conductor of electricity. The tutorial further elaborates on the solubility of KOH, highlighting that compounds with potassium are very soluble. It also covers the ionic charges of potassium and hydroxide ions. Finally, the video identifies KOH as a strong base and a strong electrolyte, concluding that KOH is indeed a strong electrolyte.
