Sodium Hydroxide, NaOH, Is a Very Strong Base

question 33

Multiple Choice

Sodium hydroxide, NaOH, is a very strong base. If a concentrated solution of this base were to spill on a latex glove you were wearing, it would feel like regular water. If the solution were to land directly on your skin, however, it would feel very slippery. Why?

• A)The sodium hydroxide solution is reacting with your skin oils and transforming them into soap, which feels slippery.
• B)The strong NaOH solution lifts the oil directly out of the skin cells and you feel the oil as a slippery sensation as it floats on the skin surface.
• C)NaOH kills skin cells on contact. The dissolved skin cells feel slippery because the cells still contain the natural oils of the skin.
• D)One of the properties of sodium hydroxide is that it is slippery. You are simply not able to sense the the slippery feel through a latex glove.
