A rough & ready method involves memorising three numbers â 3, 5 and 8 â and the fact that 1 km in miles is approximately equal to the first of these numbers divided by the second, or alternatively the second divided by the third. That is: 1 km â 3/5 or 5/8 miles.
Ammonium chloride solutions with ammonia are used as buffer solutions. In paleontology, ammonium chloride vapor is deposited on fossils, where the substance forms a brilliant white, easily removed and fairly harmless and inert layer of tiny crystals.
Excretion of ammonium - type 4 renal tubular acidosis. 1  In type 4 RTA, the key defect is impaired ammoniagenesis. The kidneys produce and excrete ammonia to buffer acid. The normal renal response to metabolic acidosis is the generation of additonal ammonia (NH3) which buffers acid (H+) to form ammonium (NH4+). This is a critical mechanism to eliminate acid and without this buffering, the excretion of the daily load of acid would result in a urine pH of below 3.
