Warna Warni Kem-Isteri.....Ok La, Chemistry (Post Khas Dengan Gambar Lebih Besar Daripada Biasa)

bismillahirrahmanirrahim



hurm...sementara menunggu caramel apple siap,


aku rse ade baiknya aku manfaatkan blog utk improve akademik aku


atau lebih spesifik lagi, subjek kimia, yg markahnye sipi2 je sem lpas


tambahan plak, lpas cny, ade test kimia


jd, terimalah...


(baca dgn nada org panggil artis wt psembahan)


secara langsung dari makmal kimia a-level intec


KIMIA??!!










hurm... ni ialah gambar reaction iodine with sodium thiosulfate (Na2S2O3)


the blue-black precipitate is mixture of iodine with starch indicator


tujuan ltak starch ialah


after that, the clear solution is the part


when the iodine is mixed with sodium thiosulfate


where the reaction will form sodium iodide and sodium tetrathionate


or...


I2 + Na2S2O3 > NaI + Na2S4O6


jd, eksperimen ni sbnanye nk tgk oxidation of metal and non-metallic elements


by halogen


dlm kes ni, iodine oxidise S from +2 kpd +2 setengah


(nampak cm klaka an charge +2 setengah tp terimalah hakikatnye)


komen sdiri: mende ni bapak sumpah best gler!!!


mase mula2 ltak iodin ngn starch, gelap je


pastu ble ltak sodium thiosulfat tuh, ltak setitik je,


xgoncang xape, tetibe je, lame2, die jd clear sdiri, mmg SMART!!!






ni plak adelah eksperimen to show that a higher halogen can displace its lower halide


which means F2 can replace Cl-


Cl2 can replace Br-


Br2 can replace I-


dlm kes ni, Cl2 replace I- from KI


so, productnye ialah KCl and I2


lpas reaction, solution is added with cyclohexane (organic solvent)


jd, yg purple ialah I2 dlm organic solvent


while yg brown kt bawah ialah I2 in water (dlm exam tulis pale brown)


komen: bese r, just kaler je yg wt aku teruja, huhu






aku tau ni adelah reaction Fe+2 ngn halogen



tp, aku xigt mne satu Cl2, Br2 dan I2



kalau xsilap,



dr kiri, Br, Cl, dan I



ni plak sbnanye juz reaction when Pb(NO3)2 is mixed with KI



the product actually is yellow precipitate



which is the color of PbI2 to show the presence of I-



tp sbb aku ni suke men2 ngn end product,



aku campur air sampe jd 3 layers of varying yellow solution

lawa2~~~



ni plak adelah HI gas



yg terhasil ble I- gas react dgn conc. H2SO4 dan pastu dipanaskan



eksperimen ni pun utk uji the presence of I-



yg ni best sbb gas ni bkaler an?



ye r, kt shah alam ni asek2 gas kaler itam a.k.a. asap kenderaan je



hurm, asap ni bau mmg menarik r,



bau jam ban, siyes




ni plak ialah cyclohexane, ek? haha, xdelah



ni ialah.....



hurm, ape yg aku cbe nk kongsi skali kt sini



dlm kita wt eksperimen pnah x kita perhatikan



knape mula2 mende tu kaler camtu,



pastu boley tukar kaler bila campur ngn menatang ni?



kalau tgk, cth mudah, Fe+2, kaler ijau



tp bila hilang satu elektron, jd Fe+3, dh jd kaler coklat



kita spatutnye rase kagum r



cmne Allah jdkan,



sbb ilang satu elektron yg kecil sekecik2nye tu,



mende tu dh tukar kaler, dh tukar sifat dan mcm2 r



subhanallah~



k r, apple caramel pun da masak



da serve da pon



(gler 2 jam aku wat post ni!!! gler3!!!)



kdg2 bile terlalu sibuk, letih, kne gak bg reward kt diri kite



kne gak rehat cm kucing ni, comel je ble tdo







cumilcumilcumilcumilcumilcumilcumil~~~


till then,


assalamualaikum

ainazirah said...

wargh.. jeles3~ wuwuwu..
knape korg leh maen2 ngan experiment?? yyy??

EmberPen said...

weh, serius aku nk tumpang lab ko utk blaja kimia. aku kne ada org bimbing aku utk subjek tu.huhu
weh, kucing cumil tu blh bg aku kat gmi x? gler cumil ah dia tu!!

Annas Alias said...

zue

huhu, tq very much.

knape x caye lak? aku animal-lover kot, korg je xtau, huhu

ainazirah

errr, sbb kitorg alg??

muhd

meh r intec, ramai dak2 sini terer kimia. dan kucing tu...A BIG NO!! SHE'S MINE!! haha

xpahamla plak...
mamende ni??xderla...sajer je...
syg cikgu Farhana!!
tengok kucing tu tringat kucing DM kisas...tp ni lg comey
