Acids and bases are really important in our daily day life. So let’s start with telling the definitions of them. Starting with acids, they are a substance which dissociates in water in order to produce one or more hydrogen ions. Also we can write H+ instead of hydrogen ion. Bases have the same definition, although the difference is that it firm hydroxide ions instead of hydrogen ions. We can write OH- instead of hydroxide ion. All alkali is bases but not all bases are alkali. However a base is normally a metal oxide or hydroxide. If the base is soluble in water, it is given a special name alkali If people know the properties of acids and bases, they could make it in a better possible way. Properties of Acid and Bases
Acids release a hydrogen ion into water solution.| Releases a hydroxide ion into water solution| Acids neutralize bases in a neutralization reaction| Neutralize acids in a neutralization reaction | Acids corrode active metals| Denature protein|
Acid turn blue litmus to red| Bases turn red litmus to blue| Acid taste sour| Bases taste bitter|
Acidic and basic are two extremes that describe a chemical property chemicals. The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. So basically a neutral water should have a pH of 7, but usually we see that they might be 6.8 or 7.5. That is still drinking water. Usually water with pH of 7 is much expensive than the average one which is usually from 6.8 to 7.5 .
Some common acid and bases with their pH scale :
Common Acids| pH| Common Bases| pH|
Fresh milk| 0.1
6.5| Human saliva
Milk of magnesia...
