特色训练 3

以框图为背景的无机综合推断

1.已知 A、B、C、D 是中学化学的常见物质,且 A、B、C 均含有同一种元素。 在一定条件下它们之间的相互转化关系如图所示(部分反应中的 H2O 已略去)。

请回答下列问题: (1)若 A 可用于自来水消毒,D 是生产、生活中用量最大、用途最广的金属单 质,加热蒸干 B 的溶液不能得到 B,则 B 的化学式可能是__________;工业 上制取 A 的离子方程式为___________________________________________。 (2)若 A 是一种碱性气体,常用作制冷剂,B 是汽车尾气之一,遇空气会变色, 则反应①的化学方程式为_______________________________________ ______________________________________________________________。 (3)若 D 是氯碱工业的主要产品之一,B 有两性,则反应②的离子方程式是 _______________________________________________________________。 (4)若 A、C、D 都是常见气体,C 是导致酸雨的主要气体,则反应③的化学方 程式为________________________________________________________。 某同学将搜集到的一定量的酸雨保存在密闭容器中,每隔一定时间测酸雨的 pH,发现在起始一段时间内,酸雨的 pH 呈减小趋势,用离子方程式解释原 因:__________________________________________________________ ________________________________________________________________。 解析 (1)氯气常用于自来水消毒,则 A 为 Cl2;铁是使用最广泛的金属单质,

D 是铁,则 B 为 FeCl3、C 是 FeCl2。(2)碱性气体为 NH3,汽车尾气中遇空气 变色的气体是 NO。 (3)常见的两性物质是 Al2O3 和 Al(OH)3, D、 C 分别为 NaOH 和 NaAlO2,故 B 为 Al(OH)3。(4)导致酸雨的主要气体是 SO2,A 与 SO2 均含 有硫元素,且二者反应生成硫单质,故 A 为 H2S。酸雨的主要成分是 H2SO3, 在放置过程中被氧化为 H2SO4,酸性增强。

答案

(1)FeCl3

电解 2Cl-+2H2O=====2OH-+Cl2↑+H2↑

催化剂 (2)4NH3+5O2 ===== △ 4NO+6H2O (3)Al(OH)3+OH-===AlO- 2 +2H2O (4)2H2S+SO2===3S↓+2H2O
- 2H2SO3+O2===4H++2SO2 4

2.右图表示某固态单质 A 及其化合物之间的转化关系(某些产物和反应条件已略 去)。化合物 B 在常温常压下为气体,B 和 C 的相对分子质量之比为 4∶5,化 合物 D 是重要的工业原料。 (1)写出 A 在加热条件下与 H2 反应的化学方程式: ________________________________________________________________; (2)写出 E 与 A 的氢化物反应生成 A 的化学方程式: ______________________________________________________________; (3) 写 出 一 个 由 D 生 成 B 的 化 学 方 程 式 :

________________________________________________________________ _______________________________________________________________; (4)将 5 mL 0.10 mol· L-1 的 E 溶液与 10 mL 0.10 mol· L-1 的 NaOH 溶液混合。 ① 写 出 反 应 的 离 子 方 程 式 :

______________________________________________________________; ②反应后溶液的 pH________7( 填“大于”“小于”或“等于”) ,理由是 _______________________________________________________________; ③加热反应后的溶液,其 pH________(填“增大”“不变”或“减小”),理 由是____________________________________________________。 解析 常见的固体单质除了金属之外还有 B、C、Si、P、S、I2,而能在空气

中反应生成气体化合物的只有 C、S。由 A 在加热条件下可与氢气反应,B、 C 的相对分子质量之比为 4∶5,确定 A 是单质硫,因为 SO2 和 SO3 的相对分 子质量之比恰好为 4∶5,硫酸是重要的工业原料,化合物 E 应为 H2SO3。将 5 mL 0.10 mol· L-1 的 E(H2SO3)溶液与 10 mL 0.10 mol· L-1 的 NaOH 溶液混合,

- 两者恰好完全反应,所得溶液为 Na2SO3 溶液,由于 SO2 3 +H2O

HSO- 3 +

OH-,所以溶液显碱性。根据水解的特点可知加热溶液可以促进水解。 答案 △ (1)S+H2=====H2S

(2)H2SO3+2H2S===3S↓+3H2O △ (3)C+2H2SO4(浓)=====CO2↑+2SO2↑+2H2O(其他合理答案也可)
- (4)①H2SO3+2OH-===SO2 3 +2H2O ②大于

Na2SO3 是强碱弱酸盐,水解后

溶液呈碱性 pH 增大

③增大

- 水解是吸热反应,加热促使 SO2 3 水解程度增大,因而
