Final answer:
Bases, such as soaps, are characterized by being slippery to the touch. They also form aqueous solutions that act as electrolytes and can vary in strength from weak to strong.
Step-by-step explanation:
Bases are substances that have certain characteristic properties. When bases are dissolved in water, they form aqueous solutions that are also electrolytes, much like acids. Bases can be strong or weak, influencing their degree of ionization in solution. An important property of many bases, particularly when discussing their physical feel, is that they are often slippery to the touch. This is because substances like soaps, which are bases, have molecules that can lather and create a slippery texture. In contrast to their taste, which is typically bitter, the textural sensation of a base is more akin to the slippery feeling one might experience when handling soap.
