Going through a basic PPM calculation by volume or by mass will help to cement the concepts you need to understand. For mass, imagine you have 0.98 liters of water with 0.2 g of salt dissolved in it, noting that 1 L of water = 1 kg of mass, so the total mass in the example is ...
Stock Solution: In the laboratory, usually, we prepare dilute solutions from a preserved solution with a higher concentration. This solution with a higher concentration is called the stock solution. Answer and Explanation:1 According to Beer's law: ...
recording results on a meter in nephelometric turbidity units (NTU). You must calibrate the instrument to convert between NTU and parts per million (ppm), because
Recycling is a pretty simple concept: take something that isn't useful anymore and make it into something new instead of just throwing it away. It can be anything from recycling old paper into new paper, to making an old hubcap into a decorative birdbath. In reality, recycling can get...
Solutions are quantitatively prepared by first having a detailed calculation on the amounts of the solute and the solvent needed to have the desired concentration. This is needed to accurately prepare the solution so that it can be used in different quantitative assays....

available and cheap. You would have to make a stock solution of 12g of espom salt in one liter of tap water. Then you dilute the solution 1/100 (e.g 1 tea spoon in 495 g of water), This should rise your water of 100 ppm aproximatly and your water will be quite hard at this ...
So, in a stocked tank, the level should read 0 ppm (parts per million).The bacteria in an established tank should exist in high enough numbers to break down nitrites the moment they are produced – leading to a zero reading when tested....
localized air gap but with much more flux leakage causing localized gap loss and interference. In some cases, this loss due to localized gap can exceed the core loss itself. Due to the localized nature of the air gap in a gapped ferrite core, it does not exhibit good temperature stability...
Unfortunately, your fish doesn’t have hands to give himself a good scratch. Instead, he will brush against objects to make the itching stop, which can result in scrapes and damaged skin.While some species of fish are more prone to Ich than others, such as tetra, no fish is immune to ...
