How many mL (to the nearest mL) of 0.187-M KF solution should be added to 590. mL of 0.143-M HF to prepare a pH = 3.90 solution?
Homework Answers
HF is a weak acid having Ka=7.2×10^-4 . (Note: This value of Ka is given in my reference book, if some other value is given in yours then change calculation accordingly)
On Mixing KF in HF solution, it will form acidic buffer solution, For we can apply Henderson equation from there we will get volume of KF solution.
Answer : 2630mL
