电离平衡图像问题是电解质溶液相关题型中的重点和难点,也是高考命题的热点。突破图像问题要按以下三步走:识图像、想原理、找联系。识图像,是指识别图中坐标的含义,包括原点、起点、拐点、终点的含义,数据与数量级、曲线和平台的含义等。想原理,是指找到电离平衡图像涉及的原理,影响平衡移动的因素。找联系,是指将图像与原理联系起来分析题设问题,做出正确的判断。以下从五种电解质平衡图像进行分析。
The problem of ionospheric balance image is the key and difficult problem in the related problems of electrolyte solution, which is also the hot topic of college entrance examination proposition. Break through the image of the problem to follow the following three steps: knowledge image, think the principle, to find contact. Recognition of images refers to the meaning of the coordinates of the recognition map, including the origin, starting point, inflection point, the meaning of the end point, data and magnitude, the meaning of the curve and the platform. Think of the principle, refers to find the principle of ionospheric equilibrium image, the factors that affect the balance of movement. To find contact, refers to the image and the principle linked to analyze the problem set to make the right judgments. The following is an analysis of five electrolyte balance images.
