emi:
how is the test for PH done ? in the experimental Techniques ?
and wat are the experimental improvements ?
twilight:
u can test pH using litmus paper or universal indicator solution
improvements can be using a colorimeter (this is related to universal indicator)
or a more accurate way of measuring pH is using a pH meter
