Acids and Bases Definition Acids Acids have long been known as a unique class of chemicals whose aqueous solutions have the characteristics of being sour. Acids alter the colour of litmus paper from red to blue when they react with metals and give H2 gas, and when they react with bases, ...

Acids and bases react with each other in what is called aneutralizationreaction. The reaction produces salt and water and leaves the solution closer to a neutral pH than before. One common test of whether an unknown is an acid or a base is to wet litmus paper with it.Litmus paperis a p...
Acids and bases are assigned a value between 0 and 14, thepHvalue, according to their relative strengths. Purewater, which is neutral, has a pH of 7. A solution with a pH less than 7 is considered acidic, and a solution with a pH greater than 7 is considered basic, or alkaline. ...

Acids and bases have different physical properties 1. Acids are also corrosive and change litmus paper to red. Effects Changes in pH in the body lead to physical changes. When your body has too much carbon dioxide, the blood becomes too acidic. Breathing is slowed to increase the pH in the...
