Webb[OH-] = (1.0 X 10-14)/ [2.4 X 10-3] = 4.17 X 10-12 M. pH = -log[H 3 O +] Plug the molarity of the HCl in and solve for pH. pH = -log[0.0035] = 2.46; pH = -log[H 3 O +] Plug in the pH … WebbpH = −log [H+] The square brackets around the H + automatically mean "concentration" to a chemist. What the equation means is just what we said before: for each 1-unit change in pH, the hydrogen ion concentration changes ten-fold. Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic).

Webb18 jan. 2024 · Hydrogen Ion Concentration (pH) Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A decrease in pH below 7 shows an increase in acidity (hydrogen ions), while an increase in pH above 7 shows an increase in alkalinity (hydroxyl ions). Webb27 sep. 2016 · I got a pH of 4.92. By inspection, NaOH is a strong base, as it dissociates to release OH− ions into solution. It contains 1 OH− that corresponds with one H+ in acetic acid. Both the acid and base have one equivalent of H+ or OH− respectively, so there is a 1:1 molar ratio. Thus, the base neutralizes the weak acid HC2H3O2 to an equimolar extent.
