Question

in some of the following reactions you are asked to observe the smell of the solution. Use the st to mix the solution and then pull it out and very, vary carefully smell it. Avoid getting the solu tirring rod tion on your nose and rinse with water i J you do touch it. The only smells we are looking for are: (vinegar /no vinegar) or (ammonia/ no ammonia). The colors are pink or clear. Be sure to mix each solution. F. Add about 0.5 mL (about 15 drops) of 1.0 M acetic acid solution in a small test tube. Add a drop or two of the phenolphthalein indicator. Carefully record the smell by smelling a stirring rod used to mix the solution. Add drops of 1.0 M NaOH until a reaction occurs. Carefully record the smell after the reaction. Ao vinega Smells: Colors: Narmes: Vlnear clear in k -acetic- sodium +phenslphthalein acid dw xide Mol. Eqn: HC2H302 (g) + lonic Eqn. Net lonic Eqn: G.

Explanation / Answer

F)

Molecular equation:

CH3COOH (aq.) + NaOH (aq.) ------------> CH3COONa (aq.) + H2O (l)

Ionic equation:

CH3COOH (aq.) + Na+ (aq.) + OH- (aq.) ------------> CH3COO- (aq.) + Na+ (aq.) + H2O (l)

Net ionic equation:

CH3COOH (aq.) + OH- (aq.) -----------> CH3COO- (aq.) + H2O (l)

G)
Molecular equation:

CH3COONa (aq.) + HCl (aq.) ---------> CH3COOH (aq.) + NaCl (aq.)

Ionic equation:

CH3COO- (aq.) + Na+ (aq.) + H+ (aq.) + Cl- (aq.) ----------> CH3COOH (aq.) + Na+ (aq.) + Cl- (aq.)

Net ionic equation:

CH3COO- (aq.) + H+ (aq.) ----------> CH3COOH (aq.)

H)

Molecular equation:

CH3COOH (aq.) + CH3COONa (aq.) -----------> No net reaction occurrs

I)

Molecular equation:

NH3 (aq.) + HCl (aq.) -----------> NH4Cl (aq.)

Ionic equation:

NH3 (aq.) + H+ (aq.) + Cl- (aq.) -----------> NH4+ (aq.) + Cl- (aq.)

Net ionic equation:

NH3 (aq.) + H+ (aq.) -----------> NH4+ (aq.)

J)

CH3COOH (aq.) + HCl (aq.) ---------> No net reaction occurrs

K)

Molecualr equation:

2 Al (s) + 3 Cu(NO3)2 (aq.) -------------> 2 Al(NO3)3 (aq.) + 3 Cu (s)

Ionic equation:

2 Al (s) + 3 Cu2+ (aq.) + 6 NO3- (aq.) ------> 2 Al3+ (aq.) + 6 NO3- (aq.) + 3 Cu (s)

Net ionic equation:

2 Al (s) + 3 Cu2+ (aq.) ------------> 2 Al3+ (aq.) + 3 Cu (s)
