i face difficulty in Q where we hav to arrange compounds/aromatic compounds in increasing order of acidity r basicity,please tell me easy way to solve such arranging sequences Q quickly.
Acidity and basicity are determined by the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. An increase in acidity is caused by an increase in the concentration of H+ ions, while an increase in basicity is caused by an increase in the concentration of OH- ions.
pH is a measure of the concentration of H+ ions in a solution. A low pH indicates high acidity, while a high pH indicates high basicity. A change in pH by one unit represents a tenfold change in acidity or basicity.
The most common way to measure acidity and basicity is by using a pH meter or pH strips. These tools measure the concentration of H+ or OH- ions in a solution and give a numerical value on a scale of 0-14.
Acids are substances that release H+ ions in water, while bases are substances that release OH- ions in water. Acids have a sour taste, can corrode metals, and turn litmus paper red. Bases have a bitter taste, feel slippery, and turn litmus paper blue.
Common acids include lemon juice, vinegar, and battery acid. Common bases include baking soda, ammonia, and bleach. It's important to note that some substances may act as acids or bases depending on the solution they are in.
