Hello,

Could you please provide a detail explanation as to how to find each of these steps.

The ionization constant of a very weak acid, HA, is 5.2×10-9. Calculate the equilibrium concentrations of H3O+, A-, and HA in a 0.040 M solution of the acid.

Determine the concentrations of all species at equilibrium and the solution pH.

[H3O+] =  mol/L

[A-] =  mol/L

[HA] =  mol/L

pH =
