coffeenlucia Posted August 20, 2015 Report Share Posted August 20, 2015 If I use the product "pH Up and Down" 1 in my EE to change the pH of water, will this be viewed negatively by IB graders? Are they looking for students to manually alter pHs (eg through adding sulfur to lower pH)? 1: http://www.homedepot.com/p/Hydroponics-Organic-pH-Testing-and-Adjusting-Kit-VPTK4/202985176?MERCH=REC-_-nosearch2_rr-_-NA-_-202985176-_-N Reply Link to post Share on other sites More sharing options...
Purple Joystick Posted August 21, 2015 Report Share Posted August 21, 2015 You really haven't given us the full situation. I at least don't really see the problem. Can you tell us what you're trying to do, and why IB graders might think it's bad? If your research question involves changing pH, then I don't personally see a problem with finding something to make it easier for yourself. If you really aren't sure, maybe ask your supervisor or do some research to make sure it's alright. Reply Link to post Share on other sites More sharing options...
