The ionic composition in units of mg/m3 of an atmospheric aerosol in a tropical

Question

The ionic composition in units of mg/m3 of an atmospheric aerosol in a tropical rain forest is: SO42-: 207 NO3-:18 NH4+:385 K+:180 Na+: 247 The pH of the aerosol is 5.22. Use this data to calculate the total positive and negative charge "concentration" (mol/m3) in the aerosol and suggest reasons that might account for any discrepancy in anionic and cationic charge.

Explanation / Answer

PH = 5.22
we know that pH = -log [H+]
5.22 = - log [H+]
so log [H+ ] = -5.22
[H+] = inverse log (-5.22)
= 6.026*10-6 M since M = mol /L or mol / m3
