Question: In some solutions, the concentration of $ H_2{O^{+}} $ remains constant even when small amounts of strong acid or strong base are added to them. These solutions are known as:
Options:
A) Ideal solutions
B) Colloidal solutions
C) True solutions
D) Buffer solutions
Show Answer
Answer:
Correct Answer: D
Solution:
Solutions which resist the change in the value of pH when small amount of acid or base is added to them are known as buffers.
