Apple juice has a pH of 2.9 and water has a pH of 7. Which substance has a higher concentration of hydro noun ions and how much higher is it

Respuesta :

cec4

D
If your pH is lower, it has more Hydronium ions 
As a rule, for every decrease in pH, there is 10 times more H3O+ so since it is 4.1 there should be a bit more than 10^4. So it has to be D
