从误差概念出发,提出与忽略水的离解的相对误差(E_W),弱酸离解常数(K_0)~2关联的[H~+]近似计算的一般判别式:C_(HA)>(1-E_W)([H~+]_r+K_W/(E_W·K_0))。并应用此判别式,提出一种关于极稀或极弱酸水溶液[H~+]计算式的选择方法。
Based on the concept of error, a general discriminant of approximation [H ~ +] associated with weakly acid dissociation constants (K_0) ~ 2: C_ (HA)> (1-E_W) ([H ~ +] _ r + K_W / (E_W · K_0)). And by using this discriminant, a selection method for the formula of [H ~ +] for very dilute or very weak acid aqueous solution is proposed.
