Stock nitrate tov - Ua kom 1000 ppm N Tshuag tov, dissolve 0.7218 g KNO3 (qhuav) hauv dej deionized. Ntxiv 1 mL preservation tov ces dilute mus rau 100 mL.
Yuav ua li cas koj ua nitrate txheem tov?
Txhawm rau khaws cov khoom lag luam nitrate ntxiv 1 mL ntawm CHCl3 rau 500 mL ntawm cov tshuaj hauv Tshuag. 1. Dilute tus qauv 100 mg/L kom ua 2 mg/L tus qauv. Siv tus qauv no los ntsuas qhov tseeb ntawm cov khoom siv nitrate.
Koj ua li cas KNO3?
Production. Potassium nitrate tuaj yeem tsim los ntawm sib txuas ammonium nitrate thiab potassium hydroxide. Lwm txoj hauv kev ntawm kev tsim cov poov tshuaj nitrate yam tsis muaj cov khoom lag luam ntawm ammonia yog ua ke nrog ammonium nitrate, pom nyob rau hauv cov ntim dej khov tam sim, thiab cov poov tshuaj chloride, yooj yim tau los ua cov ntsev tsis muaj sodium.
Koj khaws cov tshuaj nitrate li cas?
Cov tshuaj nitrate tuaj yeem khaws cia ntev txog rau lub hlis siv chloroform (CHCl3). Txhawm rau khaws cov txheej txheem nitrate ntxiv 1 mL ntawm chloroform rau 500 mL ntawm cov tshuaj nitrate. (qhov piv ntawm qhov hnyav molecular N rau NO3 yog 0.138): 7200 mg/L KNO3 x 0.138=1000 mg/L nitrate nitrogen tov.
Yuav ua li cas koj ua nitrate tov los ntawm sodium nitrate?
6.5 QC Tshuag (1,000 ppm) yaj 0.1371 gntawm sodium nitrate (NaNO3) hauv 100 ml. dej tsis muaj nitrate. ' Cov tshuaj no ruaj khov rau ib hlis. Tshuag nitrate tov (6.5) rau100 mL nrog dej tsis muaj nitrate.
