Sulfuric acid, hydrochloric acid, and nitric acid are some of the common strong acids. Acids have several properties. They turn blue litmus paper red. They react with metals to produce hydrogen gas. For instance, when zinc reacts with hydrochloric acid, hydrogen gas is released. Acids also ...
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 ...

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. ...
