Use 0.5 mL of thioglycollic acid R in this test.<\/p>\n Dissolve 0.160 g in 5 mL of dilute acetic acid R. Carry out the complexometric titration of zinc (2.5.11). 1 mL of 0.1 M sodium edetate is equivalent to 17.95 mg of ZnSO4<\/sub>,H2<\/sub>O.<\/p>\n In a non-metallic container.<\/p>\n","protected":false},"excerpt":{"rendered":" Edition: BP 2025 (Ph.
