Using the Lewis concept of acids and bases, identify the Lewis acid and base in each of the following reactions: Fe(NO3)3(s)+6H2O(l)→Fe(H2O)63+(aq)+ 3NO3−(aq) NH3(g)+HCl(g)→NH4Cl(s) Drag the appropriate items to their respective bins.

Answer :

(1) is a Lewis-base and is a Lewis-acid.

(2) is a Lewis-base and is a Lewis-acid.

Explanation :

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

(1) The given balanced chemical reaction is:

In this reaction, is an electron pair donor and is an electron pair acceptor.

Thus, is a Lewis-base and is a Lewis-acid.

(2) The given balanced chemical reaction is:

In this reaction, is an electron pair donor and is an electron pair acceptor.

Thus, is a Lewis-base and is a Lewis-acid.
