Calculate the pH of 0.020M carbonic acid, H2CO3 after both dissociations. Ka1=4.45x10^-7, Ka2=4.69x10^-11
Calculate the pH of 0.0150 M H2CO3 For H2CO3, Ka1 = 4.46 x 10-7, Ka2 = 4.69 x 10-11 Answer: pH = 4.09 (acidic form for diprotic) Please help me show work! I don't understand how to solve problems like this. The answer is here.
Calculate the pH and concentration of CO3^2- in a 0.25 M solution of carbonic acid, H2CO3. Ka1= 4.4 x 10^-7 Ka2= 4.7 x 10^-11
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?)
