The concentration of an acid IS A MEASURE OF THE QUANTITY OF ACID DISSOLVED IN WATER THAT IS DESIGNATED BY MOLARITY.
Acids are always aqueous solutions, that is they are always dissolved in water. The concentration of an acid refers to the quantity of hydrogen ions that are present in the acid. If an acid contain a large quantity of hydrogen ion, it will be described as concentrated acid and if it contains a little quantity of hydrogen ion it will be described as diluted acid. The quantity of hydrogen ion [pH] in acids ranges from 1 to 6; 1 is very acid acidic and 6 is the least acidic.
