extent of hydrolysis
« on: May 16, 2013, 10:33:07 AM »
How can you decide the rate of hydrolysis in different compounds?
Please explain taking mgcl2,alcl3,pcl5,sicl4,ccl4 into account.

The extent of the hydrolysis can be measured/predicted by the equilibrium constant for the hydrolysis reaction (a so called hydrolysis constant (see Wikipedia at http://en.wikipedia.org/wiki/Hydrolysis_constant )

I think they want the chloride to be a constant and for you to evaluate the acidity of each of the cations in each of the salts. You should do this through the formula z^2/r (which I assume you learned) and find the correct acidity ratio based on what you got (you should have a table for those.. if not, look it up). If it's very strongly acidic you can expect the hydrolysis to be quite extensive.. possibly going to an oxide or hydroxide (or oxo anion in extreme cases). For feebly acidic cations, you'll see very slight hydrolysis but no hydroxides or oxides will form
