ENVR107 – Lab 9 – Mt Tolmie Fieldtrip

Thursday, March 18th 2010, ENVR107 students from Camosun College conducted a fieldtrip to the local park, Mt Tolmie (Lat: N48° 27’’ 23’ Long: W123° 19’’ 34’) in Victoria, BC. The aim of the fieldtrip was to get familiar with Ecosystem Field Form and accompanying field books (Handbooks 25 (White) & 28 (Red)). Read the rest of this entry »

CHEM121 – Experiment 2

CHEM121 – Experiment 2 – Preparation of a Standard Solution and the Analysis of an Unknown Acid.

Purpose: To use Xylenesulphonic acid (XSA) from Lab1 as a primary standard for the standardization of a sodium hydroxide solution, and use the sodium hydroxide to determine the weight of an acid that reacts with a ratio of: one mole sodium hydroxide to one mole of unknown acid.

Purpose

The reason for this experiment was to determine if water hyacinths are able to successfully absorb contaminants such as Zinc and Copper from an aqueous solution and also possible methods to improve results in the experiment for future classes. Read the rest of this entry »

Report ENVR206 – Constructed Wetlands

ENVR206B – Constructed Wetlands for Remediation Purposes

Stefan Martensson C03347318
Definition:
Constructed wetlands are artificially built marshes built to treat human wastewater and stormwater. They have four key components:
• Wastewater
• Soil and drainage materials (such as pipes and gravel)
• Plants (both above and below the water)
• Micro-organisms Read the rest of this entry »

Report – ENVR110 – A Study of the Relationship of Relative Humidity and Temperature

A Study at Camosun College, Lansdowne Campus of the Relationship of Relative Humidity and Temperature

ENVR 110, Camosun College

November 20, 2009

Introduction:

Relative humidity is a ratio expressed as a percentage of the moisture in the air to the moisture it would contain if it were saturated at the same temperature and pressure (Oxford Concise Science Dictionary, 2006).  The maximum amount of water vapor that can be contained in the air is dependent on temperature.  A given volume of warm air can hold more water vapor before it precipitates than colder air can. Factors that influence relative humidity include: altitude, cloud cover, pollution, air temperature, regulated temperature in buildings and wind. Read the rest of this entry »

Report – ENVR206B – Phytomining

Phytotechnology
Over the last 10years the science behind using organic matter to extract natural resources have been developed and tested all over the planet. This technology can be used for extracting metals from the soil for economic profit – phytomining, for ecological/biological profit – phytoremediation or both. Heavy metals, i.e. chromium, arsenic, cadmium, lead, mercury, and manganese are big problems in the environment, but these metals are also expensive. If a way to extract the contaminants, even in small amounts, from the soil at a low cost, one could ‘swat two flies in one go’ by first, and primarily, remediate the heavy metals and later extract the metals from the plants and re-use them.

Report – CHEM120 – Determination of Water Hardness using EDTA

CHEMESTRY 120-02                                                   2009-11-17
DETERMINATION OF WATER HARDNESS USING E.D.T.A.

Stefan Martensson C0347318
Lab Partner: Danielle

Procedure: Please refer to handout ‘Experiment #7’ and page 35-38, Chemistry 120 Lab Manual, 2009 Edition, Camosun College. Plus additional handout: Report and Calculation Guide.

Theory:
Hard water is water that has high mineral content (mainly calcium and magnesium ions). Hard water minerals primarily consist of calcium (Ca2+), and magnesium (Mg2+) cations, and sometimes other dissolved compounds such as bicarbonates and sulfates. Calcium usually enters the water as either calcium carbonate (CaCO3), in the form of limestone and chalk, or calcium sulfate (CaSO4), in the form of other mineral deposits. Hardness in water can cause water to form scales and a resistance to soap. It can also be defined as water that doesn’t produce lather with soap solutions, but produces white precipitate (scum) (Wikipedia, 2009). Read the rest of this entry »
