The video tutorial explains the concept of bases, substances that produce hydroxide ions in solution. Bases often feel slippery and can be corrosive, similar to acids. They are also electrolytes, capable of conducting electricity. Common bases include liquid ammonia, used as a household cleaner, and magnesium hydroxide, used as an antacid. Caustic lime is another base used in mortar production and drain cleaners.
