Question

furnishes positive ions other than H3O+ ions and negative ions other than OH− in aqueous solution.

• A. Alkali
• B. Salt
• C. Acid

Answer 1

The correct option is B Salt

Salts contain anions and cations. And these are other than $H_3{O}^{+}$and ${\mathrm{OH}}^{-}$.

For example:

$NaCl\left(s\right)\stackrel{H_{2}O}{\to }{\mathrm{Na}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right){\mathrm{CaCl}}_2\left(s\right)\stackrel{H_{2}O}{\to }{\mathrm{Ca}}^{2+}\left(\mathrm{aq}\right)+2{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)KCl\left(s\right)\stackrel{H_{2}O}{\to }{K}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$
