Question

2. As NH4OH is added to an HCl solution, the pH of the solution
A) increases as the OH- concentration decreases
B ) increases as the OH- concentration increases
C ) decreases as the OH- concentration decreases
D ) decreases as the OH- ion concentration increases

Answer 1

Answer:

c

Explanation:

Nh4OH + HCL ---> NH4Cl + H3O

so ph decreases as H3O increases

and OH also decreases

Answer 2

When NH4OH is added to a solution with HCI, the pH of the solution B ) increases as the OH- concentration increases.

Why would the solution increase?

NH₄OH is a strong base as a result of the presence of the OH compound which is a base as well. Bases have high pH and acids have low pH.

This means that as the OH- concentration increases, the solution is being made to be more basic which would lead to the pH rising.

In conclusion, option B is correct.
