Consider the reaction of $F{e}^{3+}$ and $SC{N}^{-}$in the aqueous phase:

$F{e}_{(aq)}^{3+}+SC{N}^{-}(aq)Fe(SCN{)}_{(aq)}^{2+}$

a$.$ What is the name of the $SC{N}^{-}$ion?

b$.$ What is the effect of adding NaCl on the rate of reaction? Explain your answer $($neither $N{a}^{+}$nor $C{l}^{-}$ do interact with the reacting species or produced one$).$

c$.$ What is the effect of substituting water $($the solvent$)$ with methanol? Explain your answer and $Fe(SCN{)}^{2+}$ are all soluble in methanol$).$
