Acids, Bases and pH | Good Science

Define acids, bases and neutral solutions, in terms of hydrogen ions and hydroxide ions. Compare the properties and uses of acids and bases. Describe how pH is a measure of the acidity or alkalinity of a solution, and explain how it can be adjusted. Describe the use of pH indicators for distinguishing between acids, bases and neutral solutions.

If given the name, is the word acid in the name? •Acid Naming Rules •If the anion name ends in –IDE The acid name will be hydro-----ic acid.


A major chemical spill will usually result in the immediate evacuation of the area, if not the entire building. For example :the uncontrolled release of ammonia from a gas cylinder in an unventilated enclosed area. The volume is large and may represent a high risk to persons in the area. A minor chemical spill is one that the individual can ...

458 CHAPTER 13 Carboxylic Acids 13.1 What Are Carboxylic Acids? The functional group of a carboxylic acid is a carboxyl group, so named because it is made up of a carbonyl group and a hydr oxyl group (Section 1.7D). Following is a Lewis structure of the carboxyl group, as well as two alternative representations of it:
