• Yog hais tias koj xav mus ua ib tug kev hloov ntawm cov xim zog thiab ntau cuab kev, muab lub txiv hmab kua txiv concentrate es tsis txhob ntawm lub niaj zaus.

lwm txoj kev

Cov neeg uas muaj xav li cas los ua invisible number case yuav nyiam lub idea ntawm kev siv ib tug ntau yam sib txawv ntawm cov tshuaj raws li lub ntsiab khoom siv rau lub daim card xov xwm. Tseeb: rau espionage thiab cov txawj ntse xov xwm haum ntau yam, tab sis tsis pub leejtwg paub cov neeg ua hauj yuav tsum nco ntsoov, nrog kev pab los ntawm ib co ntawm cov reagents qhia txhua ntawm lawv.

Rau cov xyaum ua tej yam nrog xov xwm zoo tagnrho:

• Phenolphthalein (qhia los ntawm dej qab zib);
• Dilute vinegar los yog acetic acid (yuav saib ib cov lus, ntsw nws nyob rau hauv liab qhwv broth);
• rooj ntsev (txaus rau cov nyiaj nitrate);
• tooj liab sulfate (sodium iodide los yog xav tau ammonium hydroxide) ;
• hlau sulfate (manifested dej qab zib);
• maize los yog qos hmoov txhuv nplej (yuav tsum tau rau kev nyeem ntawv lub iodine tov).

Tam sim no koj paub ntau yam txog yuav ua li cas yuav ua rau pom number case - koj yuav mus tshawb!
