thanks for your reply Borek, can u tell equation of this equilibrium problem so that i can solve it further. THat would be really helpful. Once again, thanks for your reply.

Hi again, I have another question. A 1L sol'n of a compound, NaC3H5O3 has an initial con'c of 0.1M. An unknown number of moles of Hcl is then added to bring a final solution to a Ph of 3.77. How many moles of HCl were added and what is the common name of this type of problem? Can anyone pls...

Homework Statement A sol'n contains Cu+2(aq) and Zn+2 ions each at a con'c of 0.1M. Hydrogen sulphide gas is bubbled up into sol'n and dissociates having an initial con'c of 0.1M. Whats the pH of the final solution? Will any precipate form? I don't know how to start the problem. Pls help me...
