Answer:
Acids that partially dissociate are weak acids, while acids that fully dissociate are strong acids.
Step-by-step explanation:
The pH scale range from 0 to 14. A pH of 7 is neutral; below it is acidic while a pH above 7 is basic.
While low pH might be an indication of a strong acid, a high pH on the pH scale indicates a base or alkaline.
On the other hand, when it comes to the degree of ionization in water, a strong acid is the one that completely ionizes in water while a weak acid partially ionizes in water.
Hence, of all the available options, only the second option correctly describes acids.
