Yadda Ake Yin Maganin Daidaitacce
Maganin da aka saba amfani da shi shine maganin da ake amfani da shi azaman nuni a cikin gwaje-gwaje da nazarin sinadarai daban-daban. Waɗannan mafita suna da yawan aiki kuma ana amfani da su akai-akai a cikin titrations, nazarin adadi, da kuma tabbatar da hanyoyin nazari. Shirya ingantattun mafita na yau da kullun ƙwarewa ce mai mahimmanci a cikin dakin gwaje-gwajen sinadarai. Wannan labarin zai bayyana mahimman matakai wajen shirya mafita na yau da kullun, nau'ikan mafita na yau da kullun, da aikace-aikacen su na aiki.
Matakin Shiri
1. Shirya Kayayyaki da Kayan Aiki
Mataki na farko wajen samar da mafita ta yau da kullun shine shirya kayan aiki da kayan aiki da ake buƙata. Ga jerin kayan aikin da ake buƙata:
– Sinadaran Tsarkakakku (abubuwan da aka saba amfani da su)
– Daidaitaccen daidaiton nazari
- Auna kofin ko pipette mai girma dabam dabam
- kwalbar Volumetric
– Ruwan da aka tace ko kuma aka cire daga jiki
– Safofin hannu da gilashin kariya
Tabbatar kana amfani da sinadarai masu tsafta kuma koyaushe ka duba ranar ƙarewa kafin amfani.
2. Tantance Mayar da Hankali Kan Maganin
Tantance yawan ruwan da ake buƙata shine mataki na farko wajen samar da mafita ta yau da kullun. Sau da yawa ana bayyana yawan ruwan da ake buƙata ta hanyar molarity (M), wanda shine adadin moles na ruwan da ake buƙata a kowace lita na ruwan da ake buƙata. Tsarin da aka saba amfani da shi don ƙididdige molarity shine:
\[ M = \frac{n}{V} \]
inda \(n\) shine adadin moles na solute da kuma \(V\) shine jimlar adadin maganin a cikin lita.
Misali, idan kana son yin maganin sodium chloride (NaCl) mai nauyin 1 M a cikin lita 1, kana buƙatar ƙididdige nauyin NaCl daidai da mole 1. Yawan molar na NaCl yana da kimanin gram 58,44/mol. Don haka, kana buƙatar gram 58,44 na NaCl don yin maganin M 1.
