Question

An aqueous solution of cesium hydroxide (strong base) is used to neutralize an aqueous solution of carbonic acid (weak acid)​

Answer 1

Many acids are simple compounds that release a hydrogen cation into solution when they dissolve. Similarly, Arrhenius defined a base as a compound that increases the concentration of hydroxide ion (OH−) in aqueous solution.

Answer 2

Learning Objectives

• To recognize a compound as an Arrhenius acid or an Arrhenius base.
• To describe characteristics of acids and bases.
• To write equations of neutralization reactions.

One way to define a class of compounds is by describing the various characteristics its members have in common. In the case of the compounds known as acids, the common characteristics include a sour taste, the ability to change the color of the vegetable dye litmus to red, and the ability to dissolve certain metals and simultaneously produce hydrogen gas. For the compounds called bases, the common characteristics are a slippery texture, a bitter taste, and the ability to change the color of litmus to blue. Acids and bases also react with each other to form compounds generally known as salts.
