Ammonium Oxalate Test for the detection of Ca in the HCl extract of Plant Ash
Ammonium Oxalate Test In Plant Biochemistry Ammonium Oxalate Test is used to detect the presence of Ca in the HCl extract of Plant Ash. Experiment Observation Inference To about 20 ml of HCl extract of Plant Ash extract filtrate , a drop of dil. NH4OH is added to make the sample alkaline. Finally saturated Ammonium Oxalate (NH4)2C2O4 solution is added. s forme in the test tube. It indicates that Ca is present in the supplied sample, as the white ppt fromed if of Calcium oxalate(CaC2O4). Reaction: Ca2+(aq) of the sample + NH4C2O4(aq) → CaC2O4 (s) white ppt + 2NH4+
