Final answer:
A base can neutralize an acidic solution through a neutralization reaction, resulting in the formation of water and a salt. Salts can form various types of solutions, but only bases have the property to neutralize acids.
Step-by-step explanation:
To neutralize an acidic solution, you would use a base. When a base is added to an acid, a neutralization reaction occurs, producing water and a salt. It is important to remember that salts can dissolve in water to form neutral, basic, or acidic solutions, depending on the specific ions they release upon dissociation.
However, only a base can effectively neutralize an acid to form a neutral solution, typically with a pH of 7 when it involves a strong acid and a strong base.
