Match the following:

Matrix:

	Column I		Column II
(a)	Blood	(i)	pH = 1.5 to 3.5
(b)	Gastric juice	(ii)	pH = 11.6
(c)	Ammonium hydroxide solution (1M)	(iii)	pH = 7.36-7.42

The pH can influence nutrient availability, biological functions, microbial activity, and chemical behavior. From 0 (very acidic) to 14 (basic), the pH scale (very alkaline). 

The pH of normal blood lies between 7.35 and 7.45. The pH of the stomach fluid is usually acidic, and its volume ranges from 20 to 100 mL. (1.5 to 3.5). A 1M ammonia solution has a pH of 11.63.
