Summary
| Description08. Директна синтеза на амониум хлорид.webm |
Македонски: Експеримент во кој се демонстрира директна синтеза на амониум хлорид. Во две микропромивалки има концентрирани раствори од амонијак и од хлороводородна киселина, соодветно. Со помош на гумени пумпички се внесува воздух во микропромивалките, кој ги завлекува со себе гасовите што се растворени во вода (амонијак и хлороводород). При контактот на двете супстанци се образува цврст продукт (амониум хлорид, NH4Cl). Равенката на реакцијата е:
Степенот на дисперзија на продуктот е толку голем што се образува чад (грубодисперзен систем гасовито–цврсто). Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје.English: Chemical demonstration of a direct synthesis of ammonium chloride. Concentrated ammonia and hydrochloric acid solutions are added to two gas-washing bottles, respectively. Using rubber pumps, air (acting as gas-carrier) is injected in the gas-washing tubes causing the streams of gasses (air with ammonia i.e. air with hydrogen chloride) to collide giving solid product (ammonium chloride, NH4Cl). The chemical equation is:
The dispersion is so high that smoke is observed (smoke is a gas–solid disperse system). Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss. Cyril and Methodius University, Skopje, Macedonia.Română: Demonstrație chimică a sintezei directe a clorurii de amoniu. Soluții concentrate de amoniac și acid clorhidric se adaugă fiecare în câte o eprubetă. Cu ajutorul pompelor de cauciuc, aerul (acționând ca transportator de gaze) este injectat în eprubete, făcând ca cele două fluxuri de gaz (aer cu amoniac, respectiv aer cu acid clorhidric) să se ciocnească dând naștere unui precipitat (clorură de amoniu, NH4Cl). Ecuația chimică este:
Dispersia este atât de mare încât se observă degajarea de fum (fumul este un ansamblu de dispersie gaz–solid). Planificat și efectuat de Marina Stojanovska, Miha Bukleski și Vladimir Petruševski, Catedra de Chimie, FNSM, Universitatea Sfinții Chiril și Metodiu, Skopje, Macedonia. |
