Mercuric oxide. Mercury hlau . Thaum twg zinc reacts nrog hydrochloric acid , cov tshuaj tiv thaiv npuas vigorously li hydrogen gas yog tsim. Thaum twg zinc reacts nrog hydrochloric acid , lub xeem raj ua heev sov asenergy yog tso tawm thaum lub sij hawm cov tshuaj tiv thaiv.

Kuj paub, yuav ua li cas thaum koj sib tov hydrochloric acid thiab zinc?

Kev sib tham: Zinc yog oxidized los ntawm hydrochloricacid ua form zinc tshuaj chloride. Hauv cov txheej txheem, hydrogen gasis tsim. Cov tshuaj tiv thaiv yog muab hauv qab no. Kev nyab xeeb: HCl thiab zinc chloride yog corrosive thiab tuaj yeem ua rau tawv nqaij khaus khaus.

Kuj Paub, yuav ua li cas thaum koj muab magnesium hauv hydrochloric acid? Cov magnesium reacts nrog cov kua qaub , ua kom pom npuas ntawm hydrogen gas. (Yeem) Yog tias cov nplaim taws ntawm lub qhov cub butane sib dua yog tuav saum cov npuas tawg, lawv yuav tsim suab nrov pops li cov hydrogen ignites. Hydrochloric acid yog corrosive kua. Hydrogen gas yog tawg.

Ib yam li ib tug yuav nug, dab tsi feem ntau tshwm sim thaum koj ntxiv dilute hydrochloric acid rau cov hlau?

Hlau hauv Hydrochloric acid . Hydrogen gas, uas ua raws li ob lub tso tawm electrons txuas rau ob hydrogen ions, npuas tawm, thiab hlau atoms (tam sim no zoo them ions) raug tso rau hauv cov tshuaj. Los ntawm qhov no oxidation-reductionreaction, lub hlau hais tias corrode, los yog maj mam wearaway.

Yuav ua li cas tshwm sim thaum acid los ntawm kev sib cuag nrog hlau?

Muaj ntau, tab sis tsis yog tag nrho, hlau teb nrog kua qaub . Hydrogen gas yog tsim raws li cov hlau reacts nrog cov kua qaub tsim kom muaj ntsev. Muaj ntau, tab sis tsis yog tag nrho, hlau teb nrog kua qaub . Hydrogen gas yog tsim asthe hlau reacts nrog cov kua qaub tsim asalt.
