WebKa2 = 1.20×10–2 A: Given the molarity of H2SO4 = 0.265 M H2SO4 is a strong diprotic acid with high Ka1 value and… Q: What is the pH of a 0.590 M solution of C₅H₅NHBr (Kb of C₅H₅N is 1.7 × 10⁻⁹)? A: Click to see the answer Q: Calculate the pH of a 0.050- M Al (NO3 )3 solution. The Ka value for Al (H2O)6 3+ is 1.4 × 10−5. WebFor a polybasic acid, the dissociation constants have different value for each steps, e.g., H3A⇌H++H2A−; K=Ka1 H2A−⇌H++HA2−; K=Ka2 HA2− ⇌H++A3−; K=Ka3 What is the observed trend of dissociation constants in succesive stage? Q. Sulphurous acid (H2SO3) has Ka1=1.7×10−2 and Ka2=6.4×10−8.

WebNov 5, 2015 · Note that the pKa 1.69 is assuming H X + X X − and is taken at 1/2 of the N a X + O H X − used. Knowing that H X 2 S O X 4 has two protons, the second pKa should be taken at 150% on the plot which would give the correct pKa value of 1.99. If you had an acid with two lower pKa values then you'd see two pH transitions in the titrations. WebAssuming complete ionization, find the molarity of H2SO4 solution: Solve Study Textbooks Guides.
