A Nitrate Experiment: The Effect of Light on Color
Which light environment should we test for nitrate in? Nitrate is an important indicator of stream health. At ALLARM, the LaMotte Nitrate-Nitrogen Tablet Kit is used to measure the concentration (mg/L) of nitrate-nitrogen in water. Nitrate- nitrogen (NO3-N) measures the amount of nitrogen in the nitrate ion (NO3-) (1). Nitrate ions are a major form of dissolved nitrogen in water due to high solubility (2). Although nitrate is a necessary nutrient…

Alconox and Alconox-Liquinox are detergents used when washing…
