Desalination takes quite a lot of energy, so it is expensive. Moreover, the residue is very saline brine, which must be disposed of without causing too many environmental problems.

Like dissolves like –> Molecules with many polar groups are more soluble in polar solvents and molecules with few ion polar groups are more soluble in non polar solvents. Water- soluble vitamins can form ion-dipole interactions with water hence it is soluble.

(a) Hanging laundry means no need to use electric dryer, saving electricity and reducing the amount of fossil fuels needed to be burnt to produced that electricity, so less fumes and thus less acid rain

(b) Walk, bike or take public transport will reduce the number of vehicles used. Thus, reducing fuel emissions and pollutants. Therefore, reducing acid rain.

(c) Avoid running dishwashers and washing machines with small loads means reduce need to use dishwasher & washing machine, saving electricity and reducing the amount of fossil fuels needed to be burnt to produced that electricity, so less fumes and thus less acid rain

(d) Added insulation means reduce usage, saving electricity and reducing the amount of fossil fuels needed to be burnt to produced that electricity, so less fumes and thus less acid rain

(e) Buying locally grown produce and locally produced food will reduce the need of transportation of imports. Thus, reducing fuel emissions and pollutants. Therefore, reducing acid rain.

a) Coal-fired plants produces dust, thus, producing H2SO4 which results in haze and decrease in visibility.

b) Normal rainfall= approximately 5.6
pH of rain fall in park = approximately 4.6
