Bio Lab Help

Postby Joeli » Mon Oct 26, 2009 9:18 pm

Hi!
so, i just recently did a lab consisting on the titration of sodium carbonate with hydrochloric acid. In this case the sodium carbonate acted as a buffer.
so my question is
how would the starting concentration of sodium carbonate (1 M) will affect will affect the determination of the pka value? why?
note that other trials with less concentrated sodium carbonate (0.75 M, 0.50 M) were performed.
I will really appreciate you help!!
and thanks in advance :D
