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!
