Acid rain is rain that contains acids. The acids in this type of rain eventually end up in lakes, rivers, and groundwater. Acids decrease the pH of freshwater sources. Changes in pH may affect the organisms that live in lakes and rivers and the quality of groundwater, a source of drinking water.

Sulfur oxides, including sulfur dioxide, are chemicals that contribute to the formation of acid rain. Sulfur dioxide is released into the atmosphere when fossil fuels like coal, petroleum, and natural gas are burned to produce electricity.

What can people do to lessen the effect of energy production on the pH of freshwater sources? Check all that apply.

stop producing electricity
produce energy using water power
use electricity or energy-saving products
create technology to capture sulfur dioxide
use petroleum instead of coal to produce electricity
increase the use of coal in the production of electricity

Production of energy using water power

Using electricity or energy-saving products, creation of technology to capture sulfur dioxide are the processes that can be taken into account.

Acid rain is a very serious issue in the urban areas now a days. Acid rain forms due to the excessive production of gases like sulphur dioxide, nitrogen oxides etc which are beyond the level of absorption by the environment. This gases go up in the atmosphere and they mixes with cloud water to form corresponding sulphuric acid and nitric acid. These acids come along the rain and decrease the pH of the water bodies as well as soil.

If we start using water as the source of our energy production, then we can eliminate the use of coal and other fossil fuels which are chief sources of these gases.

If we can grow some technology to capture these gases before they are released into the environment, then also there will be less problems. Technologies like alkali bath are not so operative in large scales.

We can use electricity in boilers and other places where still, fossil fuels are brunt to produce the heat so that sulphur oxides don't come out.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
