Ph Value

pH of a solution is calculated using:

%5Ctext%7BpH%7D%20%3D%20-%5Clog%5B%5Ctext%7BH%7D%5E%2B%5D

For 0.0001 M HCl,

%5B%5Ctext%7BH%7D%5E%2B%5D%20%3D%2010%5E%7B-4%7D%20%5C%2C%20%5Ctext%7BM%7D

, so the pH is:

%5Ctext%7BpH%7D%20%3D%20-%5Clog(10%5E%7B-4%7D)%20%3D%204

Thus, the correct answer is 4.
