$(i)$ In pure water
$(ii)$ In presence of $0.1\ M AgNO_3$
$(iii)$ In presence of $2\ M aq.$ solution of $KCN$
$(iv)$ In presence of $ 1\ M aq$. solution of $Ca(CN)_2$
$(v)$ In presence of $2\ M aq.$ solution of $NH_3$
(Assuming $100\%$ dissociation of $AgNO_3, KCN$ and $Ca(CN)_2)$ and complex formation with $NH_3$ and $CN^-$ will take place.
