Transcript of Difference between Acids and Bases. : Acids and bases are two types of corrosive substances. Any substance with a pH value between 0 up to 7 is considered acidic, whereas a pH value of 7 to 14 is a base. Acids are ionic compounds that break apart in water to form a hydrogen ion (H+).
Likewise, what is an acid or a base?
By the 1884 definition of Svante Arrhenius (Sweden), an acid is a material that can release a proton or hydrogen ion (H +). Hydrogen chloride in water solution ionizes and becomes hydrogen ions and chloride ions. If that is the case, a base, or alkali, is a material that can donate a hydroxide ion (OH-).
What makes it an acid?
On the other hand, substances such as hydrochloric acid, HCl, are held together by polar ionic bonds and when placed into water the hydrogen will break away to form hydrogen ions, making the liquid acidic. HCl therefore has a very low pH and is a very strong acid.
What is acid and basic?
In chemistry, acids and bases have been defined differently by three sets of theories. One is the Arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution.
