A buffer consists of 0.27 M KHCO3 and 0.33 M K2CO3. Given that the K values for H2CO3 are, Ka1 = 4.5 x 10-7 and Ka2 = 4.7 x 10-11, calculate the pH for this buffer.
the pH will be simply given by the Henderson Hasselbalch equation :-
pKa = - log (Ka1) = - log (4.5 x 10-7) = 6.34
acid = 0.27 M
base = 0.33 M
putting these values in the equation we get :-
A buffer consists of 0.27 M KHCO3 and 0.33 M K2CO3. Given that the K values...
A buffer consists of 0.53 M KHCO3 and 0.59 M K2CO3. Given that the K values for H2CO3 are, Ka1 = 4.5 x 10-7 and Ka2 = 4.7 x 10-11, calculate the pH for this buffer.
A buffer consists of 0.24 M NaH2PO4 and 0.47 M Na2HPO4. Given that the K values for H3PO4 are, Ka1 = 7.2 x 10-3, Ka2 = 6.3 x 10-8, and Ka3 = 4.2 x 10-13, calculate the pH for this buffer.
A buffer consists of 0.24 M NaH2PO4 and 0.47 M Na2HPO4. Given that the K values for H3PO4 are, Ka1 = 7.2 x 10-3, Ka2 = 6.3 x 10-8, and Ka3 = 4.2 x 10-13, calculate the pH for this buffer. I know that the answer is 7.49 because pH = -log(6.3 x 10-8) + log(0.47/0.24). What I want to know is WHY 6.3 x 10-8 was used instead of Ka1 or Ka3. Thanks.
12. Calculate the pH and the concentration of all species in solution of 0.33 M K2CO3. For carbonic acid Ka1 = 4.3 x 10-7 and Ka2 = 5.6 x 10-11
A buffer consists of 0.34 M NaH2PO4 and 0.28 M Na2HPO4. Given that the values for H3PO4 are, Ka1 -7.2 x 10-3 Ka2 = 6.3 x 10-8 and Ka3 = 4.2x 10-13, calculate the pH for this buffer. Selected Answer: Correct Answer: [None Given] 7.12 10.02
A buffer solution is 0.387 M in H2CO3 and 0.291 M in KHCO3. If Ka1 for H2CO3 is 4.2 x10^-7, what is the pH of this buffer solution? pH =
Part A) A buffer solution is made that is 0.304 M in H2CO3 and 0.304 M in NaHCO3. If Ka1 for H2CO3 is 4.20 x 10^-7 , what is the pH of the buffer solution? pH = Write the net ionic equation for the reaction that occurs when 0.088 mol KOH is added to 1.00 L of the buffer solution. (Use the lowest possible coefficients. Omit states of matter.) PART B) A buffer solution is made that is 0.311 M...
A buffer solution contains 0.471 M KHCO3 and 0.289 M K2CO3. Determine the pH change when 0.127 mol KOH is added to 1.00 L of the buffer. pH after addition − pH before addition = pH change = __
A buffer solution contains 0.402 M KHCO3 and 0.329 M K2CO3. Determine the pH change when 0.107 mol NaOH is added to 1.00 L of the buffer. pH after addition - pH before addition = pH change
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?)
