Explanation:
It is known that when pH of a substance is more than 7 then the substance is considered basic in nature. When pH of a substance is less than 7 then the substance is considered acidic in nature.
And, when the pH of a substance is equal to 7 then it is considered neutral in nature.
The pH of given substances are as follows.
Coffee = 5.0
Orange Juice = 3.5
Milk = 6.5
Soda pop = 2.5
Battery acid = 1.0
As battery acid as very low pH therefore, it is highly acidic in nature.
Thus, we can conclude that given acids are arranged in increasing order of acidity as follows.
Milk < Coffee < Orange juice < Soda pop < Battery acid
