in class last week we were doing the pH tests on different substances... my teacher got a pH meter and added some sodium hydroxide to some water... then she told me to add a few drops of the indicator. she tested the pH with a the pH meter then she told me to add drop by drop more indicator.... at first i thought the indicator wasn't strong enough... but then she kept asking to add the indicator and measuring the change in the pH... they i realised something.... ahahahaha.... she is an idiot!!!
