|
ions or molecules that can accept H+

|
|
ions or molecules that can release H+
|
|
|
the concentration of hydrogen ions produced is equivalent
|
|
|
An increase in the alkaline component is a state of acidosis
|

not one of the above

Explanation:
Detailed explanation-1: -A base is a substance which in solution accepts hydrogen ions. For example, the base bicarbonate (HCO3–) accepts hydrogen ions to form carbonic acid: HCO3– + H+ H2CO3. pH is a scale of 0-14 of acidity and alkalinity. Pure water has a pH of 7 and is neutral (neither acidic nor alkaline).
Detailed explanation-2: -If one of those ions is H+, the solution is acidic. The strong acid hydrogen chloride (HCl) is one example. If one of the ions is OH-, the solution is basic.
Detailed explanation-3: -The most important pH buffer system in the blood involves carbonic acid (a weak acid formed from the carbon dioxide dissolved in blood) and bicarbonate ions (the corresponding weak base).
