Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trizalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers. …

Strips chemically treated with starch and cadmium iodide measure total chlorine to determine the strength of sanitizers in cleaning solutions. Furnished in plastic vial of 200 1/4” x 3 1/2” strips, with color comparison chart, which has three standards 50, 100 and 200 ppm

Normally found in water and soil as ammonia (NH₃), nitrate (NO₃), and nitrite (NO₂), nitrogen is an indispensable part of the life cycle. However, concentrations above certain levels can present problems. Thomas No. 3241S80 Utilizing the simple color…
