Using the Electrolyte Table and the Solubility Table, write (a) general molecula

Question

Using the Electrolyte Table and the Solubility Table, write (a) general molecular, (b) complete ionic and (c) net ionic equations for the mixing of the indicated reactants. Assume water is the solvent. Indicate solids by writing an (s) and weak, soluble electrolytes by (aq) after the formula. aluminum sulfide and nitric acid (a) ___ (b) ___ (c) ___ ammonia (ammonium hydroxide) and hydrochloric acid (a) ___ (b) ___ (c) ___ ammonium chloride and zinc nitrate (a) ___ (b) ___ (c) ___ aluminum and sulfuric acid (a) ___ (b) ___ (c) ___ barium sulfide and cobalt (III) acetate (a) ___ (b) ___ (c) ___ oxalic acid and sodium hydroxide (a) ___ (b) ___ (c) ___

Explanation / Answer

* Ammoium Hydroxe and Hydrochloric acid

Molecular equation: NH4OH (aq.) + HCl (aq.) -----------> NH4Cl (aq.) + H2O (l)

IOnic equation: NH4+(aq.) + OH-(aq.)+H+(aq.)+Cl-(aq.)---->NH4+(aq.)+Cl-(aq.)+H2O(l)

Net ionic equation: OH- (aq.) + H+ (aq.) ------------> H2O (l)

* Ammonium chloride and zinc nitrate

Molecular equation: 2 NH4Cl (aq.) + Zn(NO3)2 (aq.) -----> ZnCl2 (aq.) + 2 NH4NO3 (aq.)

Ionic equation: 2 NH4+(aq.)+2Cl-(aq.)+Zn2+(aq.)+2NO3-(aq.)---> Zn2+ (aq.)+2Cl-(aq.)+2NH4+(aq.)+2NO3-(aq.)

Net ionic equation: NO Net reaction Occurs.

* Aluminium and sulphuric acid

Molecular equation: 2 Al (s) + 3 H2SO4 (aq.) -------------> Al2(SO4)3 (aq.) + 3 H2 (g)

Ionic equation: 2 Al (s) + 6 H+ (aq.) + 3 SO42-(aq.) ----> 2 Al3+ (aq.)+3SO42-(aq.)+3H2(g)

Net ionic equation: 2 Al (s) + 6H+ (aq.) ------------> 2 Al3+ (aq.) + 3 H2 (g)
