Dissolved Metals and pH Water Tests for contamination by acidic water
Dissolved Metals and pH Water Tests for contamination by acidic water. Experiment for a first time science fair project. Testing only takes a few minutes per sample.
# 584 Dissolved Metals and pH in Water
Each water sample is tested for this Set of parameters: Dissolved Metals (Combined Metals Cu+2, Co+2, Zn+2, Cd+2, Ni+2, etc.) and pH in Water (2 tests per set).
Dissolved Metals test scale
#150 Dissolved Metals in Water
Colorimetric test strips. (1 test per strip)
Testing for Dissolved Metals, also referred to as Trace Metals, in tap water is very common and is very quick and easy with these
semiquantitative test strips. Each test strip result indicates the combined presence of heavy metals (Cu+2, Co+2, Zn+2, Cd+2, Ni+2, Pb+2, etc…) in water.
The color chart for this test allows you to read Dissolved Metals in micrograms/L (ugms/L) or parts per billion (ppb). The color chart was calibrated using mixed metals solution.
In the presence of one specific metal, or a high concentration of a specific metal, colors such as purple, red, or brown may appear. In this situation, matching levels based on color
intensity may be necessary to reach semiquantative results.
The Color Comparator Chart for this test reports mixed Dissolved Metals levels in water at:
<10, 20, 50, 100, 200, 400, 1000 microgms/L or ppb.
(Note: concentration units are micrograms per Liter or
parts per billion: ppb.)
Results are obtained from this test in 2 1/2 minutes.
pH test scales
# 110 pH Testing of Water
Colorimetric test strips. (1 test per strip)
This pH test is very versitile in that it can be used for Drinking Water testing, food processing, environmental applications or in any other water matrix.
pH is short for “Power of Hydrogen”. The balance of positively charged and negatively charged hydrogen ions in drinking water determines pH.
Water that has a low pH is acidic or aggressive and can corrode plumbing resulting in metal ions being present in drinking water and damages fixtures and pipes.
Water that has a high pH is basic and will leave scale in pipes and fixtures.
This test features two test pads both measuring at the same range using different color indicators. This makes color matching easier on the Color Comparator Chart than with other colorimetric tests.
The test reports water pH at the following levels:
2.0, 3.0, 4.0, 5.0, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10, 11, and 12
Results are obtained from this test in 1 minute.
