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.
Aqueous ammonium chloride reacts with aqueous sodium hydroxide to form ammonia gas, liquid water, and aqueous sodium chloride. skeleton eqtn: Aqueous sodium phosphate and liquid water are formed when aqueous sodium hydroxide reacts with phosphoric acid.
