Calculate the pH of a solution made by adding 42 g of sodium acetate, NaCH3COO, to 22 g of acetic acid, CH3COOH, and dissolving in water to make 300. mL of solution. Hint given in feedback. The K, for CH3COOH is 1.8 x 10-5 M. As usual, report pH to 2 decimal places. Answer: Calculate the pH of a solution made by adding 59 g of sodium acetate, NaCH3COO, to 22 g of acetic acid, CH3COOH, and dissolving in water...
Calculate the pH of a 0.575 M of sodium acetate (NaCH3COO). Ka for acetic acid is 1.8 × 10-5.
5. Calculate the grams of NaCH3COO required for 100.0 mL of 0.20 M CH3COOH solution to achieve a pH of 4.40. (Assume no volume change.) K = 1.8 x 10-5 6. What is the pH of 100.0 mL of buffer consisting of 0.20 M CH3COOH/0.20 M NaCH3COO after 10.0 mL of 0.20 M HC1 was added into the solution ? Kg = 1.8 x 10-5 7. The pH of a sodium acetate-acetic acid buffer is 4.80. Calculate the ratio of...
Question 14Calculate the pH of a 0.051M solution of sodium acetate (CH3COONa). The Ka for lactic acid is 1.4 × 10-4.a. 12.71b. 2.57c. 1.29d. 8.28e. 11.43
6. What mass of sodium acetate (NaCH3COO) should be dissolved in 250.0 mL of 0.30 M acetic acid (CH3COOH) to form a buffer of pH 5.0? [Ka for acetic acid is 1.8 × 10−5 ] (a) 11 g (b) 8.0 g (c) 7.5 g (d) 5.0 g (e) 1.4 g
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
7. Calculate the mass of sodium acetate (CH3COONa) that must be added to 1.00 L 0.450 M acetic acid (CH3COOH), Ka = 1.8 x 10 ) to form a pH = 5.00 buffer. Ka = 1.8 x 109.
Calculate the pH of a solution made by adding 59 g of sodium acetate, NaCH3COO, to 22 g of acetic acid, CH COOH, and dissolving in water to make 500. mL of solution. Answer:
what mass of sodium acetate, NaCH3COO, do we need to add to a 500 mL solution that contains 1.2g of acetic acid, CH3COOH, to make a buffered solution with pH 5.0. No value change when add sodium acrtate. Ka of acid is 1.76 x10-5
