A base, according to the Arrhenius hypothesis, is a chemical that produces a metal ion and hydroxide ions in an aqueous solution$\left({\mathrm{OH}}^{−}\right)$.The following equation represents the combination of $\mathrm{Sr}(\mathrm{OH}{)}_2$with water:

localid="1652608648142" $\mathrm{Sr}\left(\mathrm{OH}{)}_2\right(s\left)\stackrel{{\mathrm{H}}_2\mathrm{O}}{âŸ\P }{\mathrm{Sr}}^{2+}\right(aq)+2{\mathrm{OH}}^{−}(aq)$

$\begin{array}{lcc}\text{Strontium}& \text{Strontium}& \text{Hydroxide}\\ \text{hydroxide}& \text{ion}& \text{ion}\end{array}$

Consequently, $\mathrm{Sr}(\mathrm{OH}{)}_2$is a base

An acid, and according to Arrhenius theory, is indeed a chemical that creates hydrogen ions in either an aqueous solution $\left({\mathrm{H}}^{+}\right)$. The combination between ${\mathrm{H}}_2$and ${\mathrm{SO}}_4$ and water has been represented as follows:

${\mathrm{H}}_2{\mathrm{SO}}_3\left(aq\right)+2{\mathrm{H}}_2\mathrm{O}\left(l\right)⇄{\mathrm{SO}}_3^{2−}\left(aq\right)+2{\mathrm{H}}_3{\mathrm{O}}^{+}\left(aq\right)$

A single proton $\left({\mathrm{H}}^{+}\right)$does not exist in water; however, it quickly reacts with it to generate the hydronium ion $\left({\mathrm{H}}_3{\mathrm{O}}^{+}\right)$.

As a result, ${\mathrm{H}}_2{\mathrm{SO}}_3$is an acid.

An acid, according to the Arrhenius theory, would be a molecule capable releases hydrogen ions in an aqueous solution $\left({\mathrm{H}}^{+}\right)$The reaction among both ${\mathrm{HC}}_2{\mathrm{H}}_3{\mathrm{O}}_2$and oxygen is expressed in the form:

localid="1652608692233" ${\mathrm{HC}}_2{\mathrm{H}}_3{\mathrm{O}}_2\left(aq\right)+{\mathrm{H}}_2\mathrm{O}\left(l\right)⇄{\mathrm{C}}_2{\mathrm{H}}_3{\mathrm{O}}_2^{−}\left(aq\right)+{\mathrm{H}}_3{\mathrm{O}}^{+}\left(aq\right)$

A molecular proton $\left({\mathrm{H}}^{+}\right)$does not exist in water; however, it quickly reacts with it to generate the hydronium ion $\left({\mathrm{H}}_3{\mathrm{O}}^{+}\right)$

As a consequence, ${\mathrm{HC}}_2{\mathrm{H}}_3{\mathrm{O}}_2$is indeed an acidic.

A bases, as per the Arrhenius theory, seems to be a substance that generates a metal ion and hydroxide ions in such an aqueous solution $\left({\mathrm{OH}}^{−}\right)$. This same following equation reflects the interaction of $\mathrm{CsOH}$ using water:

localid="1652608748534" $\mathrm{CsOH}\left(s\right)\stackrel{{\mathrm{H}}_2\mathrm{O}}{âŸ\P }{\mathrm{Cs}}^{+}\left(aq\right)+{\mathrm{OH}}^{−}\left(aq\right)$

$\begin{array}{l}\text{Cesium}â€\dots â\P Ä\dots â\P Ä\dots â\P Ä\dots \text{Cesium}â€\dots â\P Ä\dots â\P Ä\dots â\P Ä\dots \text{Hydroxide}\\ \text{hydroxide}â€\dots â\P Ä\dots â\P Ä\dots â\P Ä\dots \text{ion}â€\dots â\P Ä\dots â\P Ä\dots â\P Ä\dots \text{ion}\end{array}$

As a conclusion, CsOH is a base.
