Which of the following substances is primarily responsible for soap's slippery texture?
A
water
B
carbonate
C
an acid
D
a base
Verified step by step guidance1
Understand that soap's slippery texture is related to its chemical nature and how it interacts with skin and water.
Recall that soap is typically made from the reaction of a fat with a strong base, such as sodium hydroxide, resulting in a substance called a salt of a fatty acid.
Recognize that this salt of a fatty acid is basic in nature, meaning it has a pH greater than 7, which contributes to the slippery feel.
Consider that water itself is neutral and does not cause slipperiness, while acids and carbonates do not primarily contribute to the slippery texture of soap.
Conclude that the base component in soap is responsible for the slippery texture because it reduces friction and interacts with oils on the skin, creating that characteristic feel.
