A buffer solution contains .267 m acetic acid and .295 m sodium acetate. Calculate the ph of this buffer. If .225 moles of HBr are added to 1 L of the buffer, what is the pH of the resulting solution, assuming volume does not change? please show work and post the right answer
can I get help with 3 and 4 3. A buffer solution contains 0.50 M acetic acid and 0.50 sodium acetate. Calculate the pH of this solution. (2 pts) 4. What is the pH of 2.00mL of 1,0 M HCI solution diluted to 50.0 mL? ( 2pts) Page 1 of
calculate the ph of a buffer solution that contains 1.5 M acetic acid (CH3COOH) and 0.3 M sodium acetate (CH3COONa) [Ka=1.8x10-5 for acetic acid]
A buffer solution is 0.78 M in acetic acid and 0.22 M in sodium acetate. Calculate the solution pH after adding 0.80 g of solid NaOH to 100.0 mL of the buffer solution. Ka of acetic acid is 1.8 10−5 . Assume negligible volume change.
A buffer solution contains 0.11mol of acetic acid and 0.14mol of sodium acetate in 1.00 L. What is the pH of this buffer? What is the pH of the buffer after the addition of 2
A buffer solution that is 0.10 M sodium acetate and 0.20 M acetic acid is prepared. Calculate the initial pH of this solution The K, for CH3COOH is 1.8 x 10-5 M. As usual, report pH to 2 decimal places. Answer: A buffered solution resists a change in pH. Calculate the pH when 21.2 mL of 0.031 M HCl is added to 100.0 mL of the above buffer. Answer:
You are making a pH 5.0 buffer with acetic acid (pKa = 4.75) and sodium acetate. You want the total concentration of acetate ([acetic acid] + [sodium acetate] ), to be 0.50 M. What concentrations of acetic acid and sodium acetate do you use to make your buffer? acetic acid sodium acetate
Question 4. a.) Calculate the pH of a solution initially 0.1 M in acetic acid and 0.02 M in sodium acetate. The pKa for acetic acid is 4.76. b) Calculate the pH of the buffer if you add 10 ml of 0.1M HCl to 100 ml of the buffer in part a.
please solve and show work! A buffer contains 0.50 M CH3COOH (acetic acid) and 0.50 M CH3COONa (sodium acetate). The pH of the buffer is 4.74. What is the pH after 0.10 mol of HCI is added to 1.00 liter of this buffer? A.5.57 B.4.74 C.4.38 D. 4.92 E.4.57
a buffer solution of pH =5.30 can be prepared by dissolving acetic acid and sodium acetate in water. How many moles of sodium acetate must be added to 1 L of 0.25 M acetic acid to prepare the buffer? Ka(CH3COOH)=1.8 x 10^-5
