Heat of Dilution of H2SO4
Posted: Tue May 03, 2016 8:17 am
I am looking to increase the concentration of 79% w/w sulphuric acid by mixing it with 96% w/w sulphuric acid.
The dilution of 96% to 90% sulphuric acid is exothermic, however am I right in thinking that the increase of concentration of the 79% to 90% sulphuric is endothermic. Will this absorb the heat from the exothermic dilution causing an overall endothermic mixing?
If not what is the kJ/mol produced from this?
