Question
A chemical that minimizes changes in the pH of a body fluid by releasing or binding hydrogen ion is called a _______.Question 47Select one:a.electrolyteb.acidc.alkalid.compensatione.buffer
Solution
To answer the question, let's break down the options provided:
a. Electrolyte: This is a substance that produces an electrically conducting solution when dissolved in water. It does not specifically minimize changes in pH by releasing or binding hydrogen ions.
b. Acid: This is a substance that increases the hydrogen ion concentration in a solution, which typically lowers the pH. It does not minimize changes in pH.
c. Alkali: This is a substance that decreases the hydrogen ion concentration in a solution, which typically raises the pH. It also does not minimize changes in pH.
d. Compensation: This term generally refers to the body's mechanisms to counteract imbalances, but it is not a specific chemical that minimizes pH changes.
e. Buffer: This is a substance that minimizes changes in the pH of a solution by releasing or binding hydrogen ions. It is specifically designed to maintain a stable pH.
Therefore, the correct answer is:
e. buffer
