The slippery, bitter tasting substance that you are describing is most likely a base. Bases are substances that have a pH greater than 7 and turn red litmus paper blue.
One common example of a base is sodium hydroxide (NaOH), also known as caustic soda or lye. Sodium hydroxide is a highly alkaline compound that is often used in chemical processes, cleaning agents, and manufacturing various products. It is capable of turning red litmus paper blue due to its high pH.
When dissolved in water, sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-). The presence of hydroxide ions in a solution makes it basic. These hydroxide ions can accept hydrogen ions (H+) from acids, making bases capable of neutralizing acids and forming water and a salt. This is known as a neutralization reaction.
The slippery texture associated with bases, including sodium hydroxide, is a result of their ability to react with the fats and oils on our skin, turning them into soap. This property is why bases, like sodium hydroxide, are commonly used in soaps and detergents.
It is important to remember that there are many different bases, each with unique properties and uses. Sodium hydroxide is just one example, but there are other common bases such as potassium hydroxide (KOH) and calcium hydroxide (Ca(OH)2).
