  • Dipole-dipole and the London dispersion forces with hydrogen bond are present in H2O.

H2SO4 + H2O reaction enthalpy

H2SO4 + H2O reaction enthalpy is zero because it is an acid-base reaction that neutralizes each other by the exchanging of ions of the atoms after the dissociation in water and, no external or internal energies are evolved during the process.

Is H2SO4 + H2O a buffer solution

H2SO4 + H2O is not a buffer solution as the reaction is an acid-base reaction in which atoms neutralize each other by the exchanging of ions and the solution becomes neutral which will not allow the pH vĩ đại increase more than vãn 7.

Is H2SO4 + H2O a complete reaction

H2SO4 + H2O is a complete reaction as the neutralization of atoms takes place, at the kết thúc of the reaction the formation of hydronium ions also takes place which indicates that the reaction is complete and cannot react further.

Is H2SO4 + H2O an exothermic or endothermic reaction

H2SO4 + H2O is an exothermic reaction as the bond dissociation of H2SO4 and H2O takes place they release a large amount of heat in an aqueous medium which allows the solution vĩ đại heat up and the evolution of heat takes place.

Is H2SO4 + H2O a redox reaction

H2SO4 + H2O is not a redox reaction as the oxidation states of the reactants and products are the same throughout the reaction.

Is H2SO4 + H2O a precipitation reaction
