Hi Ester, not sure if my answers are correct but hope they can help!
For 2(a), P has the most acidic water because it has the most H+ ions
For 2(b), you can use the chloride ion test (adding silver nitrate) since Q water has chloride but R water does not. Silver nitrate reacts with chloride ions to form silver chloride, which forms a white precipitate
