SUMMARY

The discussion focuses on the interaction of acids and bases in buffer solutions, specifically addressing the reaction of calcium oxide with water, which produces calcium hydroxide (CaO + H2O → Ca(OH)2). Additionally, it examines the effect of adding sodium hydroxide (NaOH) to a buffer system involving hydrofluoric acid (HF) and its conjugate base, fluoride (F-), where Le Chatelier's principle indicates that the pH will increase due to the shift in equilibrium. Lastly, the pH calculation for a solution containing 0.75 mol of acetic acid in 3.0 L of water is also discussed, emphasizing the importance of understanding buffer systems in chemistry.

PREREQUISITES

1.) i would like to know if this is right
What is the reaction that occurs when calcium oxide is added to water?
is it : CaO + H2o --> Ca(OH)2

and the second question which i have no idea to is..

Consider the buffer equilibrium:

HF(aq) + H2O(l) ---> H30(aq) + F(negative)(aq)
the HF has high conc.
The H3O has low conc.
and the F has high conc.
Using le Chat's principle, what happens to the pH of the buffer solution when a small amount of NaOH is addeD?!
thanks a bunch u guys!

help.. :(
anyone..specially the second question
 
yikes, i also have another question... please help.. :(

What pH results when .75 mol of acetic acid is dissolve din enough water to make 3.0L of solution..?
