2 Ammonium sulfate, (NH4)2SO4, is widely used as a fertiliser.In order to determine its percentage purity, a sample of ammonium sulfate fertiliser was analysed by reacting a known amount with an excess of NaOH(aq) and then titrating the unreacted NaOH with dilute HCL.(a)Ammonium sulfate r...
a基于硫酸铵((NH4)2SO4)作为为焙烧活化剂时,可以将粉煤灰中惰性的Al转变成活性的易溶出的铝盐,采用焙烧-沥滤工艺从粉煤灰中提取Al2O3。在一定条件下将(NH4)2SO4与粉煤灰混合焙烧,选用H2SO4为活性铝盐的浸出剂,探索焙烧产物中Al的溶出条件。 When based on ammonium sulfate ((NH4)2SO4) achievement for roa...
