Silicon (Si) Dirt. Na ( Sodium), B (Boron), and K (Potassium) are found in some engine oils as additives, however, they are typically indicators of coolant (Antifreeze) in oil. Levels of these elements found in quantities of 30 to 50 parts per million greater than levels in new oils are cause for concern.
الحصول على السعرJan 25, 2015· The concentration of ions in solution depends on the mole ratio between the dissolved substance and the cations and anions it forms in solution. So, if you have a compound that dissociates into cations and anions, the minimum concentration of each of those two products will be equal to the concentration of the original compound.

Of significance for fish is the fact that when the oxygen concentration falls ( through the degradation of organic wastes), the carbon dioxide concentration rises. This increase in carbon dioxide makes it more difficult for fish to use the limited amount of oxygen present.

الحصول على السعرMar 26, 2019· A concentration gradient occurs when a solute is more concentrated in one area than another. "Concentration" refers to how much of a solute there is compared to solvent. A corner of a water tank that has just had salt dumped into it, for example would have a much higher concentration of salt than the opposite end of the tank, where no salt has reached.

الحصول على السعرC N is the normal concentration in equivalents/L (Normal or N). This is also referred to as normality, which is used to express the concentration of a solute in a solution. Normality is defined as the number of equivalents of solute dissolved per liter of solution (equivalents/L = N) (Equations 1, 3, and 4).
