5.0

Sagot :

Answer:

pH = 3.5

Explanation:

HCl is a strong acid, so we can use this little formula to find the pH of the solution:

pH = -log[H3O+]

(where H3O+ is the strong acid, HCl)

So we just plug in the molarity for the concentration of the acid...

pH = -log(0.00034)

Solve.

pH = 3.468521083

And apply sig. figs....

pH = 3.5
