WebAug 17, 2015 · After adding sodium hydroxide, the amount of substance of hydronium ions is: n ( H X 3 O X +) = 10 − 4.5 × 100 × 10 − 3 = 10 − 5.5 m o l. The difference represents the … WebA plot of pH vs volume is known as a titration curve. When the acid HA is titrated with NaOH, the reaction taking place is OH − (aq) + HA (aq) → A − (aq) + H 2 O (l) A polyprotic acid has more than one ionizable proton and each proton results in an equivalence point. As the titration proceeds, the nature of the solution will change. WebApr 30, 2014 · NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. Since pH + pOH = 14 We can calculate the pH to be 13. camps for sale on 3 mile lake in port barre
