摘要
许多化学教材中对氢氧化铝是否溶于氨水等弱碱都没有明确说明,有老师通过不同的理论计算分别得出氢氧化铝难溶于氨水和能溶于氨水两种不同的结论。此文对几种不同的计算过程进行剖析,以澄清“氢氧化铝是否溶于氨水”这一问题,并通过两种计算方法都得出氢氧化铝能溶于氨水的结论。
There are no exact explanations about whether aluminium hydroxide can be dissolved in ammonia or materials belonging to weak base in many chemistry textbooks. Some teachers obtain two different results by different ways of theoretical calculation. This paper aims at analyzing different calculating processes to clarify whether aluminium hydroxide can be dissolved in ammonia and reaching the conclusion that aluminium hydroxide can be dissolved in ammonia by two ways of calculation.
