For a 0.01 M solution of carbonic acid, the concentration of CO2−3 would be: Given: pH of the solution is 4.18. Ka1 for H2CO3=4.45×10−7 Ka2 for H2CO3=4.69×10−11 Take 10−4.18=6.6×10−5

Answer»

For a 0.01 M solution of carbonic acid, the concentration of CO2−3 would be:
Given: pH of the solution is 4.18.
Ka1 for H2CO3=4.45×10−7
Ka2 for H2CO3=4.69×10−11
Take 10−4.18=6.6×10−5
