#568 Cooking Vegetables in Water Testing before and after cooking for changes.
Each water sample is tested for this Set of Parameters: Alkalinity, pH, Free Chlorine and Total Chlorine, Total Dissolved Solids (TDS) and Dissolved Metals (Combined Metals Cu+2, Co+2, Zn+2, Cd+2, Ni+2, etc.) (6 tests on each water sample).
Safe Fast Educational Fun.

Total Alkalinity and pH test scales
# 115 pH and TOTAL ALKALINITY of Water
Colorimetric test strips. (2 tests per strip)
pH and Total Alkalinity are two of the most fundamental parameters in drinking water testing as well as a great variety of other applications of water usage. Alkalinity indicates the buffering capacity of natural waters. A water is buffered if the pH does not change greatly by addition of acids or bases.
The most effective buffering action is within the pH range of water from 6.0 to about 8.5. The productivities of water can be correlated with ph, alkalinity and the buffering system.
The color charts for these tests read pH levels and Total Alkalinity in mg/L or ppm.
The Color Comparator Chart test reports levels of:
pH levels of 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 11
Total Alkalinity 0, 40, 80, 120, 180, 240, 720 mg/L or ppm.
Both tests are on the same test strip.
Results are obtained from this test in 25 seconds.
Total and Free Chlorine test scale
# 130 Total and Free Chlorine in Water
Colorimetric test strips. (2 tests per strip)
Total Chlorine and Free Chlorine test strips are used for testing
drinking water from a city water treatment system. This dual test is a convenient way of monitoring Total and Free Chlorine.
This test has been calibrated around EPA drinking water standards. Free Chlorine levels of 4.0 mg/L or greater exceeds Maximum
Contaminant Level (MCL) as recommended by EPA.
The Color Comparator Chart for this test reports mg/L or ppm of:
Total Chlorine 0.0, 0.5, 1.0, 2.0, 4.0, 10.0
Free Chlorine 0.0, 0.5, 1.0, 2.0, 4.0, 10.0
Results are obtained from this test in 30 seconds.
Total Dissolved Solids test scale
# 145 Total Dissolved Solids in Water
Colorimetric test strips. (1 test per strip)
Testing for Total Dissolved Solids (TDS) in tap water is very common and is very quick and easy with these test strips. The EPA Secondary Drinking Water Standard for for TDS is
500mg/L or ppm.
The color chart for this test allows you to read TDS in milligram/L or ppm.
The Color Comparator Chart for this test reports Total Dissolved Solids levels in water at:
0, 50, 100, 250, 500, 750 mg/L or ppm.
(Note: concentration units are milligrams per Liter or parts per million).
Results are obtained from this test in about 30 seconds.
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.
