A buffer is prepared by mixing 50 mL of 0.050 M sodium bicarbonate and 10.7 mL of 0.10 M NaOH. (Ka = 4.7 x 10^-11)
How many grams of HCl must be added to 25 mL of the buffer to change the pH by 0.07 units?
Thanks! I have been trying to manipulate the henderson hasselbach equation to get the answer for an hour now, and I can't get it, please *delete me*
