Write net ionic equations for the reactions that take place when aqueous solutions of the following substances are mixed.
A) sodium cyanide and nitric acid
B) ammonium chloride and sodium hydroxide
C) sodium cyanide and ammonium bromide
D) sodium hydrogen sulfite and potassium cyanide
E) sodium hypochlorite and ammonia
A) sodium cyanide and nitric acid
NaCN (aq) + HNO3(aq) --------> NaNO3(aq) + HCN(s)
Na+(aq)+CN- (aq) + H+(aq)+NO3-(aq) --------> Na+(aq)+NO3-(aq) + HCN(s)
CN- (aq) + H+(aq) --------> HCN(s)
B) ammonium chloride and sodium hydroxide
NH4Cl(aq) + NaOH(aq) ---------> NaCl (aq) + NH4OH(aq)
NH4+(aq) +Cl-(aq) + Na+(aq) +OH-(aq) ---------> Na+(aq) +Cl- (aq) + NH4+(aq)+OH-(aq)
C) sodium cyanide and ammonium bromide
NaCN(aq) + NH4Br (aq) ---------> NH4CN(aq) + NaBr(aq)
Na+(aq) +CN-(aq) + NH4+(aq) +Br- (aq) ---------> NH4+(aq) +CN-(aq) + Na+(aq+Br-(aq)
D) sodium hydrogen sulfite and potassium cyanide
NaHSO3(aq) + KCN(aq) -------..> NaCN(s) + KHSO3(aq)
Na+(aq) +HSO3_(aq) + K+(aq) +CN-(aq) -------..> NaCN(s) + K+(aq) +HSO3-(aq)
Na+(aq) +CN-(aq) -------..> NaCN(s) net ionic equation
E) sodium hypochlorite and ammonia
NaOCl (aq) + NH3(aq) ---------> NH2Cl(aq) + NaOH(aq)
Na+(aq) +OCl -(aq) + NH3(aq) ---------> NH2+(aq) +Cl-(aq) + Na+(aq) +OH-(aq)
OCl -(aq) + NH3(aq) ---------> NH2+(aq) +Cl-(aq) + Na+(aq) +OH-(aq) net ionic equation
