Which component of urine (“fake”) may have the greatest effect on the absorbing power of a hydrogel polymer?
What is hydrogel?
Hydrogel is a 3D network of hydrophilic polymer material that has incredible absorption and retainment properties.
Hydrogel can hold water up to 500 times its own weight.
Uses of Hydrogel: Hydrogel presents many advantages and uses that have been proven to effectively this includes, hygiene products (hair gel), Medical Applications (Wound Dressings), Drug Delivery (high-porosity structure allows drugs to be loaded and released), and Microfluidics and Converting (allows for movement or analysis of small liquid molecules)

Components of Urine
Sodium Chloride (NaCl) - there is approximately 1170 mg of sodium chloride in one litre of urine. The body uses sodium to balance other minerals in your blood and carry nutrients to different parts of the body. If the body has excess sodium, the kidney clears it and excretes it through urine.
Urea - There is approximately 9.3g of Urea per litre of urine. Urea is a diamide of carbonic acid. It is described as the chief nitrogenous end product of the metabolic breakdown in all mammals and some fishes. An excess of urea in human urine indicates that they are consuming too much protein. Amino groups removed from amino acids are converted to ammonia, which is toxic to the body so it must be converted to urea and is passed through the kidneys to be excreted in urine.
Water - After the kidneys have processed ingested water it is excreted in the form of urine. Water makes up approximately 95-96% of Urine.
Other components of Urine include urea, chloride, sodium, potassium creatinine and other dissolved ions and inorganic (sodium chloride, potassium chloride, ammonia and organic (nitrogen and phosphorus) compounds.
Glucose - Glucose is present in urine when blood in the body presents too much of it, a way of removing the excess is through urine. Excess glucose in urine can lead to kidney damage, yeast infections and UTIs

What is absorbing power?
In the context of this report, absorbing power refers to how much artificial urine hydrogel polymer is able to absorb as the different components are altered. Nappies use hydrogel polymer in the stuffing as a method to keep babies dry and free of irritation.
What are nappies? - Nappies are worn by infants who are not yet potty trained, they contain hydrogel crystals to be able to absorb and store human excrement.

The absorption power of a surface is defined as the ratio of energy absorbed over time to the radiant energy incident on it at the same time. It is the measurement of the amount of heat absorbed by an element.
