XperImenT of mEtaLs part 2 =)

salam...

pendek ckit titik noktah "salam" ari ni..hnye 3ttk noktah..knp ea??nthla..sje je..kuikui..slalu lau kwn msg or tnye "sht dop?" slalu je aku jwb alhamdulillah sht..jrg sgt ckp xbrp sht..pdhal ktika aku ckp sht,,aku tgh xsht..selsema la,skt tekakla..mcm2..dah terbiasa ckp sht smpaikan tgh skit pon g kate sht..xprsan diri sendiri tgh demam..haha..

hari ni xperimen metal of sulphuric acid bersmbung lgi..berdasarkan observation aku calcium dah jd putih..lau nk dicuci boiling tube tuh,,kene ati2 lau xmelecur tgn..magnesium ilang(larut) di sebalik asid sulphuric itu..copper xde ape2 perubahan..no reaction..n zinc tgh berbuih ag..ia mengeluarkan bubbles..tp dah mkin slow pergerakan bubbles dy drpd mgu lepas..lau xsilap,kepingan zinc tuh dah jd putih berdebu..
magnesium+sulphuric acid->magnesium sulphate+hydrogen gas
zinc+sulphuric acid->zinc sulphate+hydrogen gas
copper+sulphuric acid->no reaction

ujikaji potassium manganate (vii)..glass wool fungsinye separating the potassium manganate (vii) and metal powder..

apllying the concept of reactivity series..
metal extraction from ores(bijih)..
ore:compound of metal,carbonate,oxides,sulphate etc..

eg:
stanum ores(main compound:stanum (iv) oxides)
stanum(iv) oxide+carbon->stanum+carbon dioxide
why carbon??
-cheaper
-easily available
-more reactive

aluminium oxide+carbon->no reaction
why??krn aluminium lebih tinggi drpd carbon..
selesai!!dah nk g tdo..lewatnye..esop xtra class..mgkin esop cgu msk ngaja dulu baru aku sampai..huhu.. zzzzzzzz~
