Question

Identify h2so4(aq) as an acid or a base. write a chemical equation showing how this is an acid according to the arrhenius definition.

Answer 1

${{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}$ is an $\boxed{{\text{acid}}}$. The chemical equation that shows the acidic character of ${{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}$ in accordance with Arrhenius definition is $\boxed{{{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}} \to 2{{\text{H}}^ + } + {\text{SO}}_4^{2 - }}$.

Further explanation:

Arrhenius theory:

According to this theory, acid produces hydrogen or hydronium ions in a solution, while the base produces hydroxide ions in a solution. HCl, and ${\text{HN}}{{\text{O}}_3}$ are Arrhenius acids while NaOH and KOH are the examples of Arrhenius bases.

Consider the example of HCl. Its dissociation occurs as follows:

${\text{HCl}}\to{{\text{H}}^+}+{\text{C}}{{\text{l}}^-}$

HCl releases ${{\text{H}}^+}$ ions on dissociation and is therefore an Arrhenius acid.

The dissociation of NaOH occurs as follows:

${\text{NaOH}}\to{\text{N}}{{\text{a}}^+}+{\text{O}}{{\text{H}}^-}$

NaOH dissociates to produce hydroxide ions and is therefore an Arrhenius base.

The dissociation of ${{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}$ occurs as follows:

${{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}} \to 2{{\text{H}}^+}+{\text{SO}}_4^{2-}$

One mole of ${{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}$ dissociates to produce two moles of hydrogen ions $\left({{{\text{H}}^+}}\right)$ and one mole of sulfate ions $\left({{\text{SO}}_4^{2-}}\right)$ According to Arrhenius theory, any species that produces hydrogen ions in solution is termed as an acid. Therefore ${{\mathbf{H}}_{\mathbf{2}}}{\mathbf{S}}{{\mathbf{O}}_{\mathbf{4}}}$ is an acid.

Answer 2

  H2SO4  is an  acid

the  chemical  equation  showing  how H2SO4  is an acid  according  to the Arrhenius  definition   is as below

H2SO4  dissociate to  give  2H^+  and  SO4^2-

that is   H2SO4  = 2H^+  +  SO4^2-

According to Arrhenius  an acid  dissociate  to give H^+  ions H2SO4 is an acid  since  it dissociate  to  give  two hydrogen ions
