-and solution "A" in reaction with soduim hydrogen carbonate..(No reaction changed)...

so, for these observation..so far .. what do u think I can write....and what are the inference?..Thanks in advance for giving me such big help...

Answer 1

Your discussion should include the what each of the tests is used for, ie. universal indicator is used to detect the range of pH of a solution (ie. Very acidic - Red, Acidic - Orange/Yellow, Neutral - Green, Basic/base/alkali - Blue, Very basic/base/alkali - Purple) and phenolpthalein detects base (will turn pink), and sodium hydrogen carbonate is used to detect acids (makes CO2 gas).

Since you got no reaction with any of the test substances, you can conclude that the pH of the liquid is neutral.
