Read here to learn what is an acid, and how acids work in chemistry. An acid is the opposite of a base and has a ph of 0 to 7.

Chemistry doesn't have to be just for seasoned scientists! Read here to learn what is an acid, and how acids work in chemistry. An acid is the opposite of a base and has a ph of 0 to 7. A given amount of an acid added to the same amount of a base neutralizes the base, producing water and a salt. The definition of an acid has changed as people discovered more about chemistry. Acids were originally grouped together by their properties: They taste sour, change the color of litmus paper to red, and รขโ‚ฌยฆ
