Which of the following solutions is acidic?
A. [H30+] = 7.0x10^-7 M
B. [H3O+] = 1.5 x 10^-10 M
C. [H3O+] <7.0 X 10^-7 M
D. [H3O+] > 7.0 X 10^-7 M
E. [H3O+] = 1.0 X 10^-14
I attempted this by finding pH via the negative log of each H3O value.... which gives me a pH of 6.15 when [H3O+] is 7.0 x 10^-7 M. The way the question is worded is tricky however - it seems that only one answer is wanted (and all other questions in this assignment have only one answer) but technicially wouldn't a pH = 6.15 AND <6.15 both be acidic? and, potentially, couldnt a ph of >6.15 POSSIBLY be acidic as well if it were under 7?
