Lesson-10.1.2- understand how to use the pH scale, from 0???14, can be used to classify solutions as strongly acidic (0???3), weakly acidic (4???6), neutral (7), weakly alkaline (8???10) and strongly alkaline (11???14).PreviousLesson-10.1.4- know that acids in aqueous solution are a source of hydrogen ions and alkalis in a aqueous solution are a source of hydroxide ions.Next
