It is an extremely expensive process, not to mention the huge amount of energy required. The entire process yields a less than desirable amount of potable drinking water, all in all, desalination is an unsustainable and inefficient technique in producing potable water. Desalination is also shunned because of the environmental costs (wanton disposable of concentrated wastes impacting the local ecosystems) and the exacerbation of greenhouse gas emissions (from the large energy demand) generated.

Water soluble vitamins are polar and fat soluble vitamins are non polar. “Like” dissolves “Like”, in essence, polar molecules will combine with other polar molecules and vice versa. Water, being polar, is naturally able to dissolve its polar counterpart- the water soluble vitamin. Fat soluble vitamins are not polar, because they contain mostly Carbon and Hydrogen.

a. By hanging your laundry, you reduce the need to use the dryer. As dryer consumes electricity, the reduction of use of dryer can help reduce the use of electricity. Since electricity is produced via the burning of fossil fuel, hanging your laundry out to dry can indirectly help to reduce the emission of oxides of sulfur, which causes acid rain.

b. Walking, biking, or taking public transportation to work can help to reduce the emission of oxides of nitrogen. This is because the high temperature in car engines causes the combustion of nitrogen which produces oxides of nitrogen. With the reduction of usage of fuel dependent vehicles, the amount of oxides of nitrogen produced will decrease. Hence, a reduction in an acid rain occurrence.

c. Such activities reduces the consumption of electricity. Since electricity is produced via the burning of fossil fuel, reducing the consumption of electricity can indirectly help to reduce the emission of oxides of sulfur, which causes acid rain.

d. Adding extra insulation enables one to reduce on electricity during winter. Hot water heaters consumes electricity, but extra insulation would mean that the usage of such heating equipment is less frequent. Since electricity is produced via the burning of fossil fuel, reducing the consumption of electricity can indirectly help to reduce the emission of oxides of sulfur, which causes acid rain.

e. Buying locally grown produce goes a long way in reducing pollutants from trains, planes, trucks etc with the decline in shipping overseas produce. With the reduction of usage of fuel dependent vehicles, the amount of oxides of nitrogen produced will decrease. Hence, a reduction in an acid rain occurrence.

a. The coal fired plants release huge volume of water vapour in the combustion process. The water vapour is eventually cooled in the hilly forest, which gradually becomes visible, resembling fog, decreasing visibility. Additionally, SO3 is released in the combustion process, these cluster to form small droplets, creating smog, further reducing visibility.

b. Assume that the natural pH is 7.
When the acidic level is 10 times stronger => this corresponds to a decrease by 1 pH.
So the new pH is 6.
