Question: What is the pH of a 0.1 M solution of K2SO4? (2023)

Options:

Correct Answer: 7

Solution:

K2SO4 is a neutral salt formed from a strong acid (H2SO4) and a strong base (KOH). Therefore, the pH of the solution is 7.

What is the pH of a 0.1 M solution of K2SO4? (2023)

Step 1: Identify the components of K2SO4. It is made from potassium (K) and sulfate (SO4).
Step 2: Recognize that K2SO4 is formed from a strong acid (H2SO4) and a strong base (KOH).
Step 3: Understand that when a strong acid and a strong base react, they form a neutral salt.
Step 4: Conclude that a neutral salt in solution does not affect the pH significantly.
Step 5: Therefore, the pH of a 0.1 M solution of K2SO4 is 7, which is neutral.
