化学平衡常数、电离平衡常数、沉淀溶解平衡常数及水解平衡常数属于新课标的新增内容,这些考点已成为高考新的热点,从考生答题情况来看,有以下五个易错点。易错点1:不能正确理解平衡常数表达式化学平衡常数是指在一定温度下,当一个可逆 Chemical equilibrium constants, ionization equilibrium constants, precipitation dissolution equilibrium constants, and hydrolysis equilibrium constants are new additions to the new curriculum. These test sites have become a new hot spot for the college entrance examination. From the candidate’s answer, there are the following five error-prone points. Error-prone point 1: The equilibrium constant cannot be correctly understood Expression Chemical equilibrium constant means that at a certain temperature, when a reversible
