Kekulé's model of benzene is that it has 3 double bonds, in a ring of 6 carbons.One - Benzene isn't very reactive, so if Kekulé's model were to be correct, there would be 3 double bonds in benzene, ...
The p orbitals on each carbon atom in benzene overlapThere is delocalisation of electrons in the ring (not 3 localised C==C double bonds)This makes benzene more thermodynamically stable than predictedIt t...
pH measures the concentration of H+ (protons) in an aqueous solution. pKaCWAnswered by Charmaine W. • Chemistry tutor2583 Views
Answer: Sulphuric acid and potassium dichromate.
H2SO4 fully dissociates into ions (strong acid). It is diprotic therefore concentration of H+ ions is twice that of the acid = 0.4 M. pH = -log[H+] = -log[0.4] ...
