Calculate the pH corresponding to each of the hy-
drogen ion concentrations given below, and indicate
whether each solution is acidic or basic.
a. [H+] = 5.21 x 10^-2 M
b. [H] = 6.99 X 10^-12 M
c. (H+) = 4.13 x 10-7 M
d. [H+] = 9.97 X 10-10M

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
