Final answer:
A soap with a pH of 12 would be considered a strong base.
Step-by-step explanation:
A soap with a pH of 12 would be considered a strong base.
The pH scale is a measure of the acidity or basicity (alkalinity) of a solution. It ranges from 0 to 14, with 0 being the most acidic and 14 being the most basic. A pH of 7 is considered neutral.
Soaps are typically slightly basic in nature. They contain compounds that act as bases and accept protons from water, forming excess hydroxide ions. This is why soap solutions feel slippery.
