Can you tell me if the research paper for my science project is okay? and tell me whats wrong too. i need it.?

Question: Can A Plant Survive Being Watered by Greywater?

Variables:
*independent: Greywater
*dependent: The plant’s survival.
Hypothesis: If greywater is used to water a plant then the plant will die.
[BUT If greywater is said to be somehow good for the plants, then maybe the plant will grow.]
Background Research:
What is greywater?
What does it contain?
What are its said effects?
Are detergents alkaline or acidic?

Related Experiments on Greywater and Plant Growth:

"Greg Cloud was interested in exploring ways to reduce water usage, and decided to try an experiment with greywater and plants for his science fair project. He designed a well-controlled experiment to test whether or not greywater would damage plants. Half of the plants in his study were watered with greywater, and the other half with normal tap water. He made daily observations and measurements to assess the health of the plants in both groups. Greg’s project brought him all the way to the 2007 California State Science Fair, where he won a Science Buddies Clever Scientist award."

Myca T. also did an experiment on greywater effect. She research about the effect of Potable vs. Gray Water on Radish Growth.

Greywater

"Greywater, also known as sullage, is non-industrial wastewater generated from domestic processes such as dish washing, laundry and bathing.Greywater comprises wastewater generated from all of the house’s sanitation equipment except for the toilets (water from toilets being blackwater). Greywater is distinct from blackwater in the amount and composition of its chemical and biological contaminants (from feces or toxic chemicals)."

Information of Some People’s Use of Greywater:
"In arid communities with annual water shortages, such as California, Florida and the Southwest, gray water systems have been in use since the 1980s.
There are still some parts of the country where using gray water is actually illegal. The main concern is the potential for adverse health effects. Gray water can contain harmful microorganisms, which is why gardeners should follow some common-sense practices, such as not using it on plants that will be eaten."

Said Benefits:

Using grey water can lessen your fresh water(white water from groundwater or potable water)use and bills because you are now using something other than tapwater for watering your plants."And because the wastewater you’re using on your garden isn’t getting pumped back to the city’s wastewater treatment system, you’re also saving energy".

Is Detergent and Soap Alkaline or Acid?:
Research:

Detergents

A detergent is a substance that cleans a soiled surface. Soap is a type of detergent. Detergents are produced as bars, flakes, grains, liquids and tablets. People use detergents to wash dishes, laundry, floors, windows and other household items. Doctors even use detergents to kill germs. These cleaners contain a basic cleaning agent called surfactants or surface-active agent. Surfactants attach themselves to dirty particles then pull out dirty particles and store them until the soap and dirty particles are washed away. Most detergents contain a man-made product plus other chemicals. These other chemicals may improve cleaning ability or make the product easier to use. Soaps and detergents often have added colors or perfumes. Most surfactants used today are biodegradable.

Mercury, in its elemental form or in a chemical compound is
highly toxic. Water-soluble mercury compounds, such as mercury(
II) nitrate, can be removed from industrial wastewater by
adding sodium sulfide to the water, which forms a precipitate of
mercury(II) sulfide, which can then be filtered out.
Hg(NO3)2(aq) + Na2S(aq) ? HgS(s) + 2NaNO3(aq)
If 3.45 × 10^23 formula units of Hg(NO3)2 are reacted with excess
Na2S, what mass of HgS can be expected if this process occurs
with 97.0% yield?
