Ph of oh
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.
