Question

If a sample of a certain solution is determined to have a [H3O+] concentration of 5.22 × 10^-5 moles/liter, what is its pH? Round off your answer to one decimal place.

Answer 1

Answer:

if you know the concentration of the hydronium ion [H3O+] then you can use the following equation to find the pH of the solution.  moles/liter = Molarity.  

 

 

pH = -log [H3O+]  

pH = -log [4.6x10-1]  

 

the log of [4.6x10-1]  = -0.337

 

pH = - (-0.337)  

 

pH = 0.337 ≈ 0.3

 

 

so this is a pretty acidic solution
