REVERSIBILITY: REACTION BETWEEN IRON (II) AND SILVER IONS

reactions

may be categorized as irreversible or reversible depending on the direction they proceed.

irreversible

A reaction may be considered ________________ when practically all reactants are converted into products.

completion

If ever certain amounts of reactants are left, these are not appreciable, and the reaction is said to have gone to __________

backward reaction in an otherwise reversible process

is a kind of reaction whose products have a tendency of reacting again to give the original substances from which they are formed.

magnitude

The rates of the forward and the backward processes compete with each other but would reach a point when both would have become equal in ___________

state of chemical equilibrium

What refers to The rates of the forward and the backward processes compete with each other but would reach a point when both would have become equal in magnitude.

0.10M FeSO4 ; 0.10 M AgNO3

In step 1 what will be put in the test tube?

10mL

In step 1, how many mL of FeSO4 and AgNO3 must be put?

any precipitate formed

In step 2, when there is no further change observed, what should be filtered?

Precipitate and Supernate

In step 2, what should saved?

Fe2+; Ag+; Fe3+

For filtrate I, what presence should be tested?

0.10 M K3Fe(CN)6

To test for Fe2+, add a drop of_____________ to 1 mL of the filtrate

1.00 M HCL

To test for Ag+, add a drop of ______ to 1 mL of the filtrate

0.10 M KCNS

To test for Fe3+, add a drop of _________ to 1 mL of the filtrate.

distilled/de-ionized

a) Using a wash bottle, flash the precipitate in the filter paper with small amounts of __________ water. Drain well.

Ag+ ions

a) Test a portion of the washing for the presence of ______ by adding a drop of dilute HCl.

Ag+ ions.

Repeatedly wash the precipitate until the wash water is negative for ______

10.0 mL of 0.10 M Fe(NO3)3

In step 5, Place the filter paper with the clean precipitate in a small beaker. Add ___________. Stir well until no further change is observed.
