通常而言,IBDP 化學(xué)被視作一門(mén)比較難的學(xué)科。但對(duì)于一些小伙伴而言,IB化學(xué)卻并不那么難。這兩者并不矛盾。今天帶著大家一起看一道IBDP化學(xué)課程的真題講解(HIGHER LEVEL PAPER 2)。這道題取自于IBDP chemistry specimen paper。不多說(shuō),直接上題。
題目1:Two IB students carried out a project on the chemistry of bleach.
(b) Some of the group 17 elements, the halogens, show variable valency.
(i) Deduce the oxidation states of chlorine and iodine in the following species. [1]

(ii) Deduce, with a reason, the oxidizing agent in the reaction of hypochlorite ions with iodide ions in part (a). [1]
(iii) From a health and safety perspective, suggest why it is not a good idea to use hydrochloric acid when acidifying the bleach. [1]

題目難度:簡(jiǎn)單。
考點(diǎn)分析:考查group 17 elements的相關(guān)性質(zhì)
題目分析:第1問(wèn)Cl是+1,I是-1;第2問(wèn)oxidizing agent gains electrons,所以hypochlorite ions是oxidizing agent;第3問(wèn)因?yàn)闀?huì)產(chǎn)生有毒的氯氣;第4問(wèn)參看下面答案就很容易理解了。
正確答案:

題目2:Two IB students carried out a project on the chemistry of bleach.
(i) State the condensed electron configuration of sulfur. [1]
(ii) Deduce the orbital diagram of sulfur, showing all the orbitals present in the diagram. [1]
題目難度:簡(jiǎn)單。
考點(diǎn)分析:考查electron configuration和orbital diagram
題目分析:S最外層有6個(gè)電子,其中3s有2個(gè),3p有4個(gè);3p軌道有3個(gè),其中1個(gè)軌道有2個(gè)電子,另外2個(gè)軌道各1個(gè)電子。
正確答案:
