Acid Strength Grade 10- Science (chemistry) 11/23/2012 Mariana Boff Acids Strength Acids are substances that contain hydrogen atoms which detach to form hydrogen ions when the acid is dissolved. Acids are divided into two main categories: the strong and weak acids. The stronger ones are very corrosive and can cause severe skin burns‚ here are some examples: nitric acid (HNO3)‚ hydrochloric acid (HCl) and sulfuric acid (H2SO4). The weaker ones are less corrosive and when in touch with the

Suggested time allotment: 5 to 6 hours MODULE 2 ACIDS AND BASES In Module 1‚ you identified common properties of solutions using different methods. You learned how to report the amount of the components in a given volume of solution. You also found out that not all solutions are liquid. Some of them are solids and others are gases. Towards the end of the module‚ you investigated the factors that affect how fast a solid dissolves in water. Most of the solutions you studied in Module 1
