The following acids are arranged in order of increasing strength:

HClO< CH₃COOH < HNO₂ < HI  

The correct order of the increasing strength of their conjugate bases is:

To get a sense of the effect of cellular conditions on the ability of adenosine triphosphate (ATP) to drive biochemical processes, compare the standard Gibbs energy of hydrolysis of ATP to ADP (adenosine diphosphate) with the reaction Gibbs energy in an environment at 37 °C in which pH = 7.0 and the ATP, ADP, and Pi− concentrations are all 1.0 mmol dm−3.
