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.
Indicate whether each of the following compounds will give an acidic, basic or neutral solution when dissolved in water. 1) ammonium bromide 2) ammonium perchlorate 3) calcium hypochlorite 4) potassium nitrate. Source(s): acid base chemistry question: https://biturl.im/21YnC. Monah Â· 2 months ago.est Answer: 1) The conjugate base of the ammonium ion is ammonia. The conjugate acid of the bromide ion is HBr. Hydrobromic acid is a strong acid, but ammonium is a weak base. The solution would be acidic. 2) The conjugate base is still ammonia.
