identify the lewis base in this balanced equation: 6h2o + cr3+ → cr(h2o)63+ o h2o o cr3+ o cr(h2o)63+ done

Answer:

A. $H_2O$

Brief Explanations:

A Lewis base donates a pair of electrons. In the reaction $6H_2O + Cr^{3+}\to Cr(H_2O)_6^{3+}$, water ($H_2O$) donates a lone - pair of electrons to the $Cr^{3+}$ ion to form the complex ion $Cr(H_2O)_6^{3+}$. So $H_2O$ is the Lewis base.
