The Acidity of Juice and Soft Drinks

Introduction

Soft drinks are somewhat acidic. Along with “carbonation” (carbonic acid), many soft drinks contain citric acid and/or phosphoric acid. Fruits and fruit juices also contain acids, such as citric acid (oranges and other citrus fruits), tartaric acid (grapes), or malic acid (apples).

Objectives

The objective of this investigation is to choose a soft drink and/or a fruit juice and determine its acid concentration. Depending on the beverage that you test, it may also be possible to identify the acid, or acids, that are present in the beverage.
