50 g of HCl is mixed with 1 liter of water.

A) What H30+ concentration does the solution get?

B) What pH is the solution?

Assuming 50 grams of HCl (Hydrogen Chloride) is mixed with 1 liter (1,000 mL) of water forming a acidic solution and HCl completely ionizes in the solution.

(A)(H30+ is the same as H+ in solutions, i.e. They are interchangeable in chemistry equations)

The H+ concentration



(B)What pH is the solution?

We know the concentration of HCl in this solution is \(\frac{50}{1000} = 0.05\)

Judging on the percentage, the pH won't be an integer, applying the pH equation I found out in 8th grade:

\(pH=-\log _{10}\left(H^+\right)\)


\(pH=-\log _{10}\left(0.05\right)\)




(I could be completely wrong on my equations, haven't turned my chemistry part of brain on for half a year :P)
