Water Testing Paper

Evaluating overall results compiled by practical investigations, the water sample showed very positive results with very minimal flaws in its purity. Observing the physical properties of the sample it had no turbidity and looked relevantly clear. Data shown here may be inaccurate due to many varied factors in the lab testing. Most of the testing heavily relied on the judgment of the human eye to compare charts colours possibly resulting in human error. A low 5 m/L’s was tested each time when testing the kits presenting inaccurate data on such a small amount of testing water. Testing paper possibly suffered from many inaccurate readings due to human contact and vast exposure to air varying results each time.
High conductivity presented in the sample of 1037.3 µs/cm suggests salty or mineralised sources of water. This is proven by the common Ions in water that conduct electrical currents including sodium, chloride, calcium and magnesium suggesting the measure of high salinity within the sample. This is due to the dissolved inorganic chemicals and salts which conduct electrical currents therefor the more conductivity; an increase in salinity of 9.6ppt is shown as well. High conductivity values suggest increased amounts of dissolved chemicals are situated in the water. Large amounts of Ions suggest the water is not distilled because …show more content…
This result suggests it is from fresh water sources containing living organisms or organic matter. Carbon dioxide is the most common cause of acidity in water. Photosynthesis, respiration and decomposition all contribute to pH fluctuations due to their influences on CO2 levels. While carbon dioxide exists in water in a dissolved state, it can also react with water to form carbonic acid H2C0. It is mostly inferred that the area is surrounded by lots of eco systemic processes with lots of plant
