Such anions is actually stabilized in order to deeper extent, it offers smaller destination to have proton hence, have a tendency to work as poor feet. For that reason, brand new related acidic might be strongest because the weak conjugate foot provides strong acidic and a strong conjugate ft features weakened acidic.
This means ClOcuatro – will have maximum stability and therefore will have a minimum attraction for W. Thus CIO4 – will be weakest base and its conjugate acid HCIO4 is the strongest acid.
When aqueous ammonia is added to CuSO4 solution, the solution turns deep blue due to the formation of tetrammine copper (II) complex, [Cu(H2O)6] 2+ (aq) + 4NHstep 3 (aq) \(\rightleftharpoons\) [Cu(NH3)4] 2+ (aq), among H2O and NH3 which is stronger Lewis base. Answer: Copper (II) sulphate solution, for example contains the blue hexaaqua copper (II) complex ion. In the first stage of the reaction, the ammonia acts as a Bronsted – Lowry base. Continue reading
