Feeling slippery is a property of bases, not acids. This characteristic is due to the reaction of bases with the oils on your skin, which produces soap-like substances. When you touch a base, it reacts with the fatty acids in your skin, creating a slippery sensation.
In contrast, acids typically feel rough or sticky when they come into contact with your skin. This is because acids can cause a burning sensation or irritation, rather than the smooth, slippery feeling associated with bases.
Understanding this property can help you identify whether a substance is acidic or basic in nature. However, it’s important to handle both acids and bases with care, as they can be harmful to your skin and overall health.
