Question

1. What is the inference and observations of the reactions below
a. Fecl3 + H20
b.reaction 1. above + HCL
c. result of reaction 2 above then heated +concentrated HNO3 and heat
d. result of reaction 3 above + NH4CL AND NH4OH
2. solution of Fecl3+H20+H202+ HEAT

Answer 1

a. Observation: The reaction takes place in hot water. Like standard hydrolysis reactions, interaction of iron(III) chloride with water takes place in stages.

First iron(III) chloride dissociates. Then the iron cation interacts with water. Precipitate Fe(OH)3 forms.

Inference: The hydrolysis reaction of iron(III) chloride takes place reversibly.

b. Observation: The precipitate is dissolved.

Inference: The reaction takes place reversibly.

c. Observation: The gas is released.

Inference: The reaction takes place inreversibly.

d. Observation: The gas NH3 with an unpleasant odor is released.

Inference: The reaction takes place inreversibly.

2. Observation: A mixture of salts and gas is formed.

Inference: The reaction is exothermic.
