specifically. i know it does but why?
How does using Data logger and ph meter improve accuracy in titrations. (1 Viewer)

Reduces human error haha since you can get technology to do it for you

Well, if you're using indicator, you get a relatively large indicator error - for example:
If you are doing a titration for NaOH and HCl and use bromothymol blue, the pH range is 6.0-7.6 - the colour change occurs before pH of 7, where you expect perfect titration to be approximately. Therefore, you get something called "indicator error".
If you use a pH meter, you don't have that problem.

thank you
are there any other ways of improving accuracy? and also how is validity improved in a titration. thanks heaps.

Consistency of the results yielded (so tighter grouping), means that the results become more reliable i guess, so doing it with more repetition can improve that. reproducibility improves validity. Accuracy is hard to improve unless you decide to just use a machine that does it for you LOL
