Results of these elements undergoing Hydrolysis?

Question

Kindly give me the results (both chemical formula/equation and chemical name)

Hydrolysis of:

1)Sodium Carbonate

2)Borax

3)Cupric Sulfate

4)Cupric Chloride

5)Sodium Chloride

6)Sodium Sulfate

Thank you sooo much for your effort.

Answer 1

Neil's answer for the most part is correct. However, borax , ( sodium tetraborate ) is the conjugate base ( albeit complex structurally) of the weak acid boric acid. As a consequence it, like carbonate, undergoes hydrolysis to produce a distinctly basic solution .  

so carbonate and borax under hydrolysis, the others do not...

Answer 2

Hello,

To start,  these aren't elements,  they are compounds.

Second,  some of these don't really involve "hydrolysis" per se.  They do dissolve in water.

As an example,  the first one

Na2CO3

In water solution,  the reaction is

Na2CO3  (aq)  =>  2 Na+  +  CO3-2

Now it doesn't stop there.  H2CO3 is a very weak base,  so there is further reaction of

H+  + OH-  + CO3_2  => HCO3-  + OH-

And to a limited extens

H+  + OH-  +HCO3 -  =>  H2CO3

So sodium carbonate in water creates a very basic solution.

If the solution started out somewhat acidic,  There ia further reaction.

2H+  + CO3-2  =>  2H2CO3  =>  H2O + CO2 (g)

Sodium carbonate is the only one on the list which undergoes this kind of reaction.  The others are pretty straightforward and only go into water solution as ions.
