Which solution below has the highest concentration of hydronium ions?

pH = 9.82
pH = 12.6
pH = 7.93
pH = 3.21
pH = 7.00

• Chemistry -

hydronium is [OH-] ions, so you looking for the Ph that is most basic, which is your highest number 12.6

• Chemistry -

Thanks but its actually pH 3.21

• Chemistry -

The number in the pH is equal to the negative exponent of 10. So, a pH of 7 has a concentration where the exponent is -7, a pH of 9 will have an exponent equal to -9 and so on. So the lowest pH will have the highest H ion concentration. 10^-3 is bigger then 10^-9. So the answer is ph=3.21.

• Chemistry -

The solution with with the highest concentration of hydronium ions will be the solution with that appears the most acidic. In which case the solution with the smallest PH... 3.21
