2 This presentation should help you learn the basic things you need to know about acids and bases.
3 We can classify solutions wether it is an acid or base by knowing the physical and chemical properties which characterize acids and bases.
4 PHYSICAL PROPERTIES OF ACIDS AND BASES Acids turn blue litmus to red.Bases turn red litmus to blue.Acids taste sour.Bases taste bitter.Bases feel slippery.
5 CHEMICAL PROPERTIES OF ACIDS AND BASES Acids release hydrogen ion when added in water (aqueous) solution.Bases release hydroxide into water (aqueous) solution.Acids neutralize bases in a neutralization reaction.Bases neutralize acids in a neutralization reaction.Acids corrode active metals.Bases denature protein, which explains the slippery feeling on our hands when they’re exposed to bases.
6 How do we differentiate an acid from a base? Aside from their differences in their physical and chemical behaviour, we can differentiate an acid from a base by using their pH levels, which measures the acidity (for acids) or alkalinity (for bases) of a solution. An acid has a pH of 7.34 or less while a base has a pH of 7.46 or greater.
7 How are the strength of acids and bases identified? The terms “strong” and “weak” give an indication of the strength of an acid or base. The terms strong and weak also describe the ability of acid and base solutions to conduct electricity. In chemical aspects, the strength of acids and bases vary in their ability to transfer protons and produce hydronium ions in aqueous solutions.
9 What are pH indicators?A pH indicator is a weak acid or a base that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined visually. Normally, the pH indicator causes the color of the solution to change depending on the solution’s pH level.
