In a solution like blood that is buffered to minimise changes in pH, what deter- mines the pH of the solution? A. the concentration of the hydronium ions B. the logarithm of the concentration of the hydronium ions C. the ratio of the concentration of hydronium ions to hydroxide ions. D. the ratio of the concentrations of the two components of the buffer.
Option D.The ratio of the concentrations of the two components of the buffer determines the pH of the solution.
