A buffer solution is made using a weak acid, HA, that has a pKa of 6. If the pH of the buffer is 4, what is the ratio of A and HA?
A weak acid, HA, has a pKaâ = 4.50. What is the pH of a buffer solution in which [Aâ] = 10:1 to the nearest 0.01 unit? the equation given is pH= pka + log( [A-] / [HA] )
A buffer solution is made using a weak acid, HA, that has a pKa of6. If the pH of the buffer is 9, what is the ratio of Aââ¬â toHA?
A-/HA=?
