Calculate pH of 8.5e-2 M of H2CO3 provide 2 ICE tables and 2 dissociations
a 1.00 L buffer solution is 0.350 M H2CO3 and 0.500 M KHCO3. Calculate the pH of the buffer solution and the number of moles of base that can be added before the buffer solution is no longer effective. the Ka for H2CO3 is 4.3*10^-7 ( hint : what range of pH is a buffer solution effective?) pka plus or minus?)
