Ⅱ.實(shí)驗(yàn)中可測(cè)得的數(shù)據(jù):

黃銅的質(zhì)量a g。

充分反應(yīng)后在標(biāo)準(zhǔn)狀況下生成氫氣的體積為b L。

反應(yīng)前儀器和藥品的質(zhì)量為c g。

充分反應(yīng)后剩余固體的質(zhì)量為d g。

充分反應(yīng)后儀器和藥品的質(zhì)量為e g。

(1)實(shí)驗(yàn)中可供選擇的藥品除樣品外,還有:①足量的濃硫酸、②足量的稀硫酸、③氧化銅。你認(rèn)為一定要用到的藥品是________。

(2)甲同學(xué)實(shí)驗(yàn)中使用了A、E、F三種裝置,組裝時(shí)接口編號(hào)的連接順序?yàn)椋篲__________________________________。寫(xiě)出合金中鋅的質(zhì)量分?jǐn)?shù)的計(jì)算式:

(3)乙同學(xué)實(shí)驗(yàn)中測(cè)得的數(shù)據(jù)為:黃銅的質(zhì)量a g;充分反應(yīng)后剩余固體的質(zhì)量為d g。他在實(shí)驗(yàn)中使用了上圖中_______________裝置(填序號(hào)A……)。

(5)丁同學(xué)設(shè)計(jì)了另一種測(cè)定方法,他考慮使用A、C、D三種裝置,并使用了②足量的稀硫酸、③氧化銅兩種試劑,除測(cè)定黃銅的質(zhì)量a g外,還測(cè)定C裝置反應(yīng)前儀器和藥品的質(zhì)量為c g、充分反應(yīng)后儀器和藥品的質(zhì)量為e g。他能不能測(cè)定出合金中鋅的質(zhì)量分?jǐn)?shù)?為什么?

【題型分析】

實(shí)驗(yàn)題是高考必考的題型之一,在理綜卷中通常以綜合題的形式出現(xiàn)。高考題中出現(xiàn)的設(shè)計(jì)與評(píng)價(jià)型實(shí)驗(yàn)題處處都有課本實(shí)驗(yàn)的影子,卻又不拘泥于課本知識(shí)。這類試題的特點(diǎn)是將中學(xué)化學(xué)實(shí)驗(yàn)雙基知識(shí)置于新的情景之中,進(jìn)行或儀器組裝、或?qū)嶒?yàn)操作、或數(shù)據(jù)分析、或現(xiàn)象描寫(xiě)等基本知識(shí)點(diǎn)的考查,在考查學(xué)生的自學(xué)能力、思維能力、分析綜合實(shí)驗(yàn)和評(píng)價(jià)能力方面加強(qiáng)了力度。試題來(lái)源于教材,高于教材,考核全面,思維量大,區(qū)分度好,是值得高度重視的命題方向。
