19、（14分）、在分析试剂、医药、电子工业中用途广泛。回答下列问题：
(1)常温时，0.1的溶液的pH=3。


D.NaH的存在能支持可将氢元素放在第ⅦA族的观点
√
解析:第ⅦA族元素从上到下非金属性逐渐减弱,所以电负性从上到下逐渐减小,故A错误;金属元素的电负性一般小于1.8,非金属元素的电负性一般大于1.8,所以电负性的大小可以作为衡量元素金属性和非金属性强弱的尺度,故B正确;元素的电负性表示其原子在化合物中吸引电子能力的大小,元素电负性越大的原子,吸引电子的能力越强,故C正确;NaH中的H元素为-1价,则H可以放在第ⅦA族中,故D正确。
5.一般认为,如果两个成键元素的电负性差值大于1.7,它们通常形成离子键;如果两个成键元素的电负性差值小于1.7,它们通常形成共价键。
元素 Al B Be C Cl F Li
电负性 1.5 2.0 1.5 2.5 3.0 4.0 1.0
元素 Mg N Na O P S Si
