If a substance feels slippery, it is most likely a base. This is because bases have a slippery, soapy feel when they come into contact with the skin. This characteristic is due to the way bases react with the oils and fats on our skin, creating a soap-like substance.
Acids, on the other hand, typically have a sour taste and can cause a burning sensation when they come into contact with the skin. They do not feel slippery. Therefore, if you encounter a substance that feels slippery, it is more likely to be a base rather than an acid.
It’s important to handle both acids and bases with care, as they can be corrosive and harmful. Always use appropriate safety measures when dealing with these substances.
