Yeah but y wont we include 5 moles of water they are also present in solution !
if u r adding 5 moles of water, then u might as well add the 5000 moles of water that it is dissolved in!
err why wont SO4 ion split up? :s ashiqbal
no! SO4 ions are radicals, and they exist as SO4 2- ions in aqueous form, this much should be clear from various electrolysis!
