(a)Conjugate base : HS−:S2− H3O+:H2O H2PO−4:HPO2−4 HSO−4:SO2−4 CH3COOH:CH3COO− [Al(H2O)6]3+:[Al(H2O)5OH]2+ H2SO4:HSO−4 (b)Conjugate acids : OH−:H2O HCO−3:H2CO3 HPO2−4:H2PO−4 CH3NH2:CH3NH+3 CO2−3:HCO−3 ...
The solution is classified as a buffer if the molarity ratio of the weak acid-base conjugate pair is adjusted close to 1:1. Based on Le Chatelier's principle, the equilibrium must significantly shift left, such that the percent dissociation of the acid b...
Like ammonia, it is a base. A 0.10 mol·L1、 solution has a pH of 11.86. Calculate the Kb for the ethylamine, and find Ka for its conjugate acid, .Solution pH=11.86, pOH=14.001、1.86=2.14 [OH-]=7.2×103、 mol·L1、Kb(CH3CH2NH2) = 3. Pivaic acid is a monoprotic we...
