###### FREE Expert Solution

We are being asked to rank the following solutions in order of decreasing [H3O+]

0.10 M HNO2
0.10 M HC6H5O
0.10 M HClO
0.10 M HCl

Recall that acids produce Hor H3O+ in water.

Strong acids completely dissociate in water. So that we can directly calculate the [H3O+] from the concentration of the solution by mole-to-mole comparison

Weak acids, on the other hand, do not completely dissociate in water. So that we are going to use the ICE chart and Ka expression to determine the [H3O+].
