i need help with this question. any help would be appreciated.
1) What concentration Of H^+(aq) corresponds to each of the following:(a)pH=3.33,(b)pOH=3.33,(c) pH=6.78,(d)pOH=11.11?

a. pH = 3.33
pH = log(H^+)
3.33 = log(H^+)
3.33 = log(H^+)
antilog 3.33 = antilog log(H^+) or
antilog 3.33 = (H^+).
To find the antilog 3.33, punch in 3.33 on your calculator then push the !0^{x} button. Up will come
4.677 x 10^4 or 0.0004677
For questions involving pOH, just remember pH + pOH = 14.
