What are the reactants in a neutralization reaction? How to calculate volume of NaOH required for titration What is the purpose of adding an indicator during an acid-base titration? What laboratory glassware is used in a titration? Why is HCl not used in titration?
解析 B。首先写出反应方程式中各元素的化合价变化,铝元素从 0 价变为+3 价,氢元素从+1 价变为 0 价。根据化合价升降守恒,铝原子和氯化氢分子的比例为 1:3,生成氯化铝和氢气的比例为 1:1.5,化为整数比即 2Al + 6HCl → 2AlCl₃ + 3H₂。所以氯化铝的系数是 2。
