Problem- How many grams of potassium acetate must be added to 2.5 L of 0.250 M acetic acid to obtain a buffer at pH = 4.26?
Express your knowledge to solve the above question
What mass of silver chloride would be formed from mixing 250 mL of 0.240 M MgCl2 solution with 200 mL of 0.380 M AgNO3 solution? AgCl FWT = 143.32 g/mol
This is maintained by a number of buffers, such as the carbonic acid/bicarbonate system. Write out the acid-base reaction and state qualitatively how this buffer solution resists changes in pH. Given the Ka of carbonic acid, H2CO3 is 4.5 x 10-7.
