We have divided them into 7 types of exercise involving in the use of graphs to find the solution methods. Based on these ways, the authors have built 9 Sample Problems. On that basis, the authors compiled 15 drilling exercises for Test Yourself which are used for teaching and self-studying inorganic chemistry in High School. http://pubs.sciepub.com/wjce/5/1/3/wjce-5-1-3.pdf inorganic chemistry graphic method acids / bases gases aqueous solution chemistry precipitation
