Question

Hydrocyanic acid hcn is a weak acid write a net ionic equation with sodium hydroxide

Answer 1

Answer : The equation for the reaction of hydrocyanic acid with sodium hydroxide is as follows:
H−C≡N(aq.)+NaOH(aq.)→ Na−C≡N(aq) + $H _{2} O$ (aq)

This is similar to double displacement reaction and the net ionic form of the equation can be given by :
H−C≡N (aq) +  $^{-}OH$ (aq)→   $^{-}C$≡N(aq)+$H _{2} O$(aq)
