Water Quality – Determination Of Ph And Conductivi

Name: Shane d Title of Experiment : Water subtlety Determination of pH and conductivity. Date of Experiment: 4th October 2011 . affable home: pH is a measure of acidity or basicity of a solution. The pH scale ranges from 0-14 any value preserve as existence 7-14 is concidered basic, any value recorded as being 0-7 is concidered acidic and any analyte determine as having a pH of being around 7 is deemed to be pH unbiased eg H2O. Its important that piddle system should be uncomplete acidic or basicic in order for fish and opposite aquatic smell to survive. Although some aquatic anamals, plants and microorganisms croup spread out in intense conditions (eg algae in NO3 rich enviroments). pocket-sized pH levels animate the relase of metals from rocks which can force the metabolism of a fish by hampering the fishes ability to take in atomic number 8 through the gills. A quick test that can be done on location is pH paper however this method isnt accur ate. A more accurate reading can be determined with the use of a pH meter. conductivity: Measures the ability of an aqueous solution to carry an electric current. clear(p) clear weewee supply conducts poorly . Impure, dirty water conducts alot better.

Conductivity can be effecteed by temperature higher(prenominal) temperature higher conduction, the presence of inorganic turn solids eg NO3, cations present also effect the waters conductivity To measure conductivity we use a machine called a conductivity meter. Objectives: fall pH from a sample of river water. To determine the Conductance of an unknown water sample @ 25oC To depend the Total Dissolved Solids of an unknown water sample. Method: n! ail lab manual ex.3 and 4. Results: Table 1: Results for Conductivity and Ph . Calculations and Attachments: Calculation of Total Dissolved Solids (TDS) Conductivity (µS/cm) X 2/3 = dissolved solids (mg/l) 157.7µS/cm X 2/3 = 105.13mg/l Discussions: boilersuit the experiment has been a success. The pH was determined from the...If you want to describe a wax essay, order it on our website: OrderEssay.net
