WebbThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is … WebbA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization … citrus county fl murphy bed tools

Webb3 mars 2024 · The only physical answer is 9.51 ×10−8M. This now gives: [H+] = 9.51 × 10−8M [OH−] = 1.05 ×10−7M You can convince yourself that Kw still holds. And so, the pH is barely basic at 25∘C: pH = −log[H+] = 7.02 Answer link Webb12 dec. 2024 · pH = -log [H+] [H+] = [H+] from H2O + [H+] from HCl [H+] from H2O (@25ºC) = 1x10-7 M [H+] from HCl = 6.2x10-11 M ∑ = 1x10-7 + 6.2x10-11 = 1.00062x10-7 pH = -log 1.00062x10-7 pH = 6.9997 = 7.00 (2 sig. figs.)
