About this deal

This kit therefore measures total ammonium in solution. At physiological pH, nearly all ammonia will exist as ammonium in solution. Ammonia that has not bonded with chlorine during chloramination disinfection is referred to as free ammonia (both NH 4 + and NH 3). At a neutral pH and ambient temperature, almost all free ammonia exists as NH 4 +. As the pH and temperature increase, the amount of NH 3 increases and the amount of NH 4 + decreases. When chloraminated water is released, free ammonia levels increase as monochloramine reacts with various organics and bacteria in the distribution system water, satisfying the chlorine demand. Increased free ammonia levels indicate the onset of nitrification. A sudden drop in free ammonia suggests that nitrification is in process and nitrite is being formed. The free ammonia value is useful in determining the amount of free chlorine needed to increase the monochloramine residual at a booster station. The free ammonia level can be reduced by adding free chlorine at a ratio of 5:1 as Cl 2:N to guide the process and help minimize nitrification potential. Total Ammonia When the pH is low, the reaction is driven to the right, and when the pH is high, the reaction is driven to the left. In general, at around room temperature, at a pH less than 6.0, the proportion of ammonium-N plus ammonia-N as NH3 is very low and as NH4+ is very high. At a pH around 8.0 (the ammonia assay buffer pH), the proportion as NH3 is 10 percent or less.

Visual and instrumental ammonia testing kit formats that span low and high measurement ranges are offered. Test results for visual test kits use color comparators for analysis while instrumental kits rely on CHEMetrics direct-readout photometers or spectrophotometers capable of accepting a 13-mm diameter round cell

At a pH around 8.0 (the assay buffer pH), the proportion as NH3 is 10 percent or less. Laboratory methods measure ammonium-N plus ammonia-N. It is very difficult to directly determine the activity of aqueous ammonia, so instead the surrogate of ammonium-N plus ammonia-N is used.

For testing pH, you can use a liquid test kit or an electronic probe. Electronic probes can be more accurate if calibrated properly but are more expensive than their liquid counterparts. Due to this, we recommend using the API pH Test Kit. It comes with a testing vial, testing solution, color card, and a glass vial with a snap-tight cap to prevent messes. The entire kit can be used for around 250 tests and accurately tests pH within a 6.0 to 7.6 range. This is ideal for freshwater tanks, so if you have a saltwater tank (or a freshwater tank with a higher optimal pH range), you will need to look for another product, like the API High Range pH Test Kit. We highly recommend testing your aquarium or pond water regularly, to ensure it remains a safe and healthy home for your fish. Testing of levels such as pH, ammonia, and nitrite can help you determine whether you may be overfeeding, and alert you to any potential issues early, when they are more easily treatable. If your water tests show that any of your water parameters are very high or very low, it is important to take steps to correct conditions for fish health and wellbeing. Monitoring the water chemistry of the aquarium or pond will allow you to catch problems before they develop. Gaseous ammonia and its concentrated solutions must be handled with care and in accordance with OSHA (or other relevant regulatory agency’s) requirements. This is due to highly corrosive properties that pose serious health risks ranging from mild eye or skin irritation to chemical burning, depending on the concentration. Additionally, off-gassing ammonia can cause aesthetic problems like objectionable taste or odor.

Ammonia in groundwater is normal, due to microbiological processes. However, the presence of ammonia nitrogen in surface water usually indicates domestic pollution. Excess ammonia can damage vegetation and is incredibly toxic to aquatic life, especially at elevated pH and temperature levels. Aqua Ammonia Ammonium is a compound containing one nitrogen and four hydrogen atoms (NH 4 +). While ammonia is a neutral non-ionized molecule (weak base), ammonium is an ion carrying a positive charge. In addition, ammonia emits a strong odor, but ammonium does not smell at all. Since the test result is a sum of both molecular ammonia (NH 3) and ionic ammonium (NH 4 +), the preferred unit for reporting is as nitrogen (NH 3 -N). Most Hach colorimeters and spectrophotometers have the option to convert the test results between nitrogen, ammonia, and ammonium. This does not change the chemistry of the test; it only changes the units. It should be noted that while there is the same amount of nitrogen in ammonia and ammonium, the stoichiometric ratio of N to NH 3 and NH 4 + are not exactly equal due to different number of the hydrogen atoms.Our test kits measure the strength or weakness of a chemical presence according to the degree of colour saturation. Ie – if it is pale in colour, then the chemical concentration is low. If the colour is strong, then the chemical concentration is high. Simply add the reagent to the compound to be tested and match the colour gained against a colour chart included in the kit. Ammonia is an inorganic form of nitrogen that contains hydrogen. It is a plant nutrient often found naturally in water at low levels due to the decomposition of organic plant or animal matter. Higher concentrations in surface waters are toxic to aquatic life.
