C2f-h notes

C2f - acid and basesNeutralisation - pH7acid + base = salt + water(hydrophilic acid + potassium = potassium + water)Bases = oxides + hydroxides of metals              solubles = alkalies

C2f - fertilisers and crop yeildFertilisers - nitrogen                              - phosphorus                  - potassiumAlkali + acid (rod) + pH7 + evaporation +  filter slowly = crystalsEutrophication fertilisers wash into lakes. Increases nitrates + phosphates (increases growth in algae) algai blocks sunlight (plants die and rot) increase in aerobic bacteria. Uses up oxygen (cant support organisms = fish die and go to heaven)

C2h - Sodium Chloridesodium chloride is table saltElectrolytes of concentrated sodium chloride solution, cathode + anodes!Test for chlorine- Bleached paper
