Question

Consider the reaction when aqueous solutions of silver(I) nitrate and barium bromide are combined. The net ionic equation for this reaction is:?

Answer 1

`"Ag"^(+)("aq")" + Br"^(-)("aq")"` `rarr` `"AgBr(s)"`

Explanation:

Balanced molecular equation

`"2AgNO"_3("aq") + "BaBr"_2("aq")"` `rarr` `"2AgBr(s) + Ba(NO"_3)_2("aq")"`

The net ionic equation includes only those ions that participated in the reaction (formed the precipitate).

`"2 Ag"^(+)("aq")" + 2Br"^(-)("aq")"` `rarr` `"2AgBr(s)"`,

which can be reduced to:

`"Ag"^(+)("aq")" + Br"^(-)("aq")"` `rarr` `"AgBr(s)"`
