Calculate the concentrations of all species present (H2CO3,
HCO−3, CO2−3, H3O+ and OH−) in 0.017 M H2CO3. I already found the
pH to be 4.07. H2CO3 (Ka1=4.3×10−7;
Ka2=5.6×10−11).
Calculate the concentration of all species in a 0.150 M solution
of H2CO3. H2CO3], [HCO−3], [CO2−3], [H3O+], [OH−] = Enter your
answers numerically separated by commas. Express your answer using
two significant figures.
1) Calculate the pH and the concentrations of all species
present (H3O+, OH−, HIO3, and IO−3) in 0.0528 M HIO3. Ka for HIO3
is 1.7×10−1.
2) Calculate the concentrations of all species present (H3O+,
OH−, HIO3, and IO−3) in 0.0528 M HIO3.
Calculate the concentrations of all the species in a
0.487 M
Na2CO3
solution. For
H2CO3,
Ka1 = 4.2 ×10−7
and Ka2 =
