Find ph of weak base
WebThe pH of a 2.00 M solution of a strong acid would be equal to −log (2.00) = −0.30 . The higher pH of the 2.00 M nitrous acid is consistent with it being a weak acid and therefore … WebTo find pH of a weak base solution, insert concentration (M) and insert Kb value of the weak base (0.001 is input as 1E-3) calculate. pH= See the equation(s) used to make …

Web1 Answer Sorted by: 5 Since $\mathrm {p}K_\mathrm {a} + \mathrm {p}K_\mathrm {b} = 14$, you get $\mathrm {p}K_\mathrm {a} = 10.64$ for the methylammonium cation. $\ce {HCl}$ protonates methylamine. The amount of methylammonium increases by the same amount methylamine decreases. So WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base.
WebApr 5, 2024 · How to Calculate pH of a Weak Acid? The pH equation can be expressed as, pH = - log [H+] However, one must determine the value of Ka (Acid dissociation constant) to evaluate [H+]. Since in weak acids, the dissociation or ionisation process is not fully complete, computing pH for the weak acid is a bit more difficult. WebThe weak base NH3 (concentration 0,10 mol∙dm–3) is titrated with strong acid HCl (concentration 0,050 mol∙dm–3). If 25,0 cm3 of the NH3 is titrated with the HCl, calculate the pH at the equivalence point of the titration.
