1a. determine the pH of a citrate buffer that is 0.14 M citricacid (H3C6H5O7) and 0.18 M sodium citrate (NaH2C6H5O7). (What if itwere 0.14 sodium citrate and 0.18 M disodium citrate(Na2HC6H5O7)?
2a. For the origional citrate buffer in question 1a, determinewhat the pH will be if 10mL of 1.09 M HCl solution is added to250mL of the buffer?
3a. For the origional citrate buffer in wuestion 1a, determinehow much 1.09 M HCl could beadded before you excedd the effectivecapacity of the buffer. (How much 1.09 M HCl would be required toget [A-]/[HA} to equal 0.1)?
