INTRODUCTION
Acids and bases always challenged me throughout the years of learning them so when I learned I am going to face this topic again I thought it will be the best idea to a experiment for learning better therefore my aim for this project was learning the fundamentals of this topic.
Acids and bases are really important in functioning cell. Majority of them are harmful and they destroy tissues by dissolving protein. For example, sulfuric acid is a strong acid and it has ability to hold the water therefore if it poured on a live tissue it will be demolished immediately. Aqueous solutions of bases reacts with fat in cell membrane this makes bases more devastating to an organism than acids. Acids and bases aqueous solutions conduct

Acids and bases are really important in functioning cell. Majority of them are harmful and they destroy tissues by dissolving protein. For example, sulfuric acid is a strong acid and it has ability to hold the water therefore if it poured on a live tissue it will be demolished immediately. Aqueous solutions of bases reacts with fat in cell membrane this makes bases more devastating to an organism than acids. Acids and bases aqueous solutions conduct electric. Acids tastes sour, bases tastes bitter and bases are slippery. Strength of an acid or a base depends on its ionizing rate. Strong acids and bases are ionized completely therefore they have pH or pOH of 1, weak bases and acids doesn’t ionize completely so they have a ph or pOH of 3-5.

Acid and Base Theories

Until today acids and bases defined in many different ways but first modern description is done by Swedish scientist Svonte ARHENIUS in 1884. He said,

Aqueous solutions of acids give H+ ion. For example:
NaOH → Na+
+ OH−and

Aqueous solutions of bases give OH- ion for example
NaOH → Na+
+ OH−

Second description of acids and bases is found by Danish chemist J.N. Bronsted and English chemist in T.N LOWRY in
