（１）以氨水（１＋４）溶解样品，用ＸＯ作指示剂，ＥＤＴＡ滴定，测定ＺｎＣＯ３含量。（２）以１５％的硫酸铵溶解样品，用ＸＯ作指示剂，ＥＤＴＡ滴定，测定（ＺｎＣＯ３＋ＺｎＯ）含量。（３）以１５％的氯化铵溶液溶解样品，用ＥＢＴ作指示剂，ＥＤＴＡ滴定，测定（ＺｎＣＯ３＋ＺｎＯ＋ＣａＣＯ３＋ＭｇＣＯ３）含量，（４）以１６％的乙酸铵溶液溶解度样品，以ＸＯ作指示剂，ＥＤＴＡ滴定，测定了（ＰｂＣＯ３＋ＺｎＣＯ３＋

Dissolve the sample in the solution of ammonium hydroxide (1+4),use xylenol orange (XO) as an indicator and titrate with EDTA to determine the content of ZnCO 3. (2) Dissolve the sample in the solution of ammonium sulphate use XO as an indicator and titrate with EDTA to determine the content of (ZnCO 3+ZnO). (3) Dissolve the sample in the solution of ammonium chloride,use Eriochrome Black T as an indicator and titrate with EDTA to determine the content of (ZnCO 3+ZnO+CaCO 3+ MgCO 3 ). (4) Dissolve the sample in the solution of ammonium acetate,use XO as an indicator and titrate with EDTA to de...
