[8] What are acids and bases? Describe the two terms giving examples that you commonly use. Explain the term ‘pH’, its equation, and provide a few numbers representing the pH scale! Explain the term ‘Acid Rain’, its formation and its detrimental effect on environment.
acid and bases
acids is the substance which release protons or H+
bases are the substance readily accept protons
lewis acid and bases
lewis acid is the substance that readily accept pair of electrons
lewis base is the substance that readily donate the pair of electrons to the electron acceptors
examples
acid : HCl, HCN
base : NaOH, KOH, Na2CO3, NaHCO3
lewis acid : AlCl3, FeCl3
pHis the parameter used to measure the acidic strength of the substance
pH = -log[H+]
acid rain
it the rain fall take place in acidic condition due to environmental pollutions, the main cause for acid rain is due to burning of coal and fossil fuels
in acid rain either SO2 and water react or nitrogen oxide and water reacts to form acids
SO2 + H2O ----------------> H2SO4
these rain will kill the aquatic life like fishes and other species and it will destroy the forest
