I-Hydrochloric acid, njengesisombululo samanzi se-hydrogen chloride, inokubonelela ngokufanelekileyo i-ion chloride, ngaloo ndlela iququzelele ukuphendulwa kweekhemikhali.
2. Ukubaluleka kwe-hydrochloric acid kunyango lwamanzi
a. ukulungiswa kwe-pH
I-Hydrochloric acid isetyenziswa ngokuqhelekileyo ukulawula ixabiso le-pH lamanzi kwiinkqubo zokunyanga amanzi. Ngokudibanisa i-hydrochloric acid kwiimali ezifanelekileyo, i-alkalinity yamanzi ingancitshiswa kwaye ilungelelaniswe kwi-pH efanelekileyo. Oku kusetyenziswa kubaluleke kakhulu ekucoceni amanzi amdaka kunye nokucocwa kwamanzi okusela ukuqinisekisa ukuba umgangatho wamanzi uhlangabezana nemigangatho yokhuseleko.
b. Ukususwa kwesikali kunye nentlenga
I-Hydrochloric acid ikwasetyenziswa ngokubanzi ukucoca isikali kunye nokufakwa ngaphakathi kweebhoyila, iicondensers kunye nezinye izixhobo. Ezi iidiphozithi zinokuchaphazela ukusebenza kakuhle kokudluliselwa kobushushu kwesixhobo kwaye zikhokelela kumonakalo wezixhobo. Ngokunyibilikisa i-calcium carbonate kunye nezinye iidiphozithi nge-hydrochloric acid, ubomi benkonzo yesixhobo bunokwandiswa ngokufanelekileyo kunye neendleko zokugcina zingancitshiswa.
3. Ukusetyenziswa kwe-hydrochloric acid kwishishini lokutya
a. Ukusetyenziswa ekwenzeni ukutya
I-Hydrochloric acid isetyenziswa ikakhulu kwishishini lokutya ukuvelisa izongezo zokutya kunye neziqholo. Ngokomzekelo, ekuveliseni i-monosodium glutamate (MSG) kunye ne-sugar starch, i-hydrochloric acid isetyenziselwa inkqubo ye-hydrolysis yokuphucula ukucoceka kunye nomgangatho wemveliso. I-Hydrochloric acid ikwasetyenziselwa ukulawula i-pH yokutya okuthile ukuze kuphuculwe incasa yazo kunye neempawu zogcino.
b. Ukucoca Ukutya kunye nokuCoca
I-Hydrochloric acid isoloko isetyenziswa njenge-ejenti yokucoca ekusetyenzweni kokutya ukwenza inzalo kwizixhobo zokulungisa ukutya kunye nezikhongozeli. I-asidi yayo eyomeleleyo inokubulala ngokufanelekileyo ibhaktheriya kunye nezinye ii-microorganisms ezinobungozi ukuqinisekisa ucoceko kunye nokhuseleko lokutya.
4. I-Hydrochloric acid isetyenziswa kakhulu kwiilabhoratri
a. Isicelo njenge-reagent
I-Hydrochloric acid yinto eqhelekileyo esetyenziswa kwikhemikhali kwilabhoratri. Ingasetyenziselwa i-acid-base titration, ukuchithwa kweesampuli, kunye nemvula kunye nokwahlulwa kwesinyithi. Uhlalutyo lweekhemikhali ezininzi kunye neempendulo zokwenziwa kwibhubhoratri zixhomekeke ekuthatheni inxaxheba kwe-hydrochloric acid ukuqinisekisa inkqubela phambili egudileyo yovavanyo.
b. Ukulungelelaniswa koxinzelelo lwesisombululo
I-Hydrochloric acid ikwasetyenziselwa ukulawula ukugxininiswa kwezisombululo kwaye idlala indima ephambili ngokukodwa kwiimvavanyo ezifuna ixabiso elithile le-pH. Ngenxa yobume besisombululo esizinzileyo, i-hydrochloric acid sisixhobo esibalulekileyo solawulo oluchanekileyo lwemekobume yokusabela kweekhemikhali kwimifuniselo.
Isishwankathelo
Inokubonwa kolu hlalutyo lungentla ukuba i-hydrochloric acid isetyenziswa ngokubanzi kwiinkalo ezininzi ezifana noshishino lweekhemikhali, ukutya kunye nonyango lwamanzi ngenxa ye-acidity eqinile kunye nokusebenza okuphezulu. I-Hydrochloric acid idlala indima ebalulekileyo kunyango lokucholwa kwesinyithi, i-organic synthesis, unyango lwamanzi, ukulungiswa kokutya kunye ne-reagents zaselabhoratri. Ke ngoko, ukuqonda okunzulu kunye nolwazi lokusetyenziswa kwe-hydrochloric acid ibalulekile kubasebenzi abakumashishini anxulumeneyo.
Nokuba kukwimveliso yeshishini okanye kuphando lwebhubhoratri, ukusetyenziswa okwahlukeneyo kwe-hydrochloric acid kuyenza ibe yenye yeekhemikhali eziyimfuneko. Ngohlalutyo oluneenkcukacha kweli nqaku, ndiyakholelwa ukuba uzuze ukuqonda okubanzi kokusetyenziswa kwe-hydrochloric acid.
