Homework Help: chemistry lab

Posted by maura on Tuesday, March 27, 2012 at 9:57pm.

Hi, so I did a lab on acids, bases, salts and buffer solutions. After measuring the pH for a .010 M HCl solution I got a pH of 2.50. After doing a calculated pH of .010 M of HCl the answers is 2.
My question is why do you think my pH from the experimental is slightly higher than that of the calculated? And is this .5 difference really that significant?
Thanks!
