Remove the test tube with the precipitate in it and using a pipet remove the liquid above the precipitate from the test tube and place it in a new test tube. Take care not to remove any precipitate with the pipet because that will transfer some of the PbCl2 to the new test tube. Step...
To bring organs in the digestive and endocrine systems into focus, a patient will swallow a contrast media mixture, typically a barium compound. If the doctors want to examine blood vessels or other elements in the circulatory system, they will inject contrast media into the patient's ...

How can one use chemical tests to differentiate between a solution with Cl− ions and a solution with I− ions? Chemical Tests: Chemical tests are tests for compounds in which the specific reactivities to different assays are recorded. Since different compoun...
of fun to perform—it can't be used to identify allmetalsbecause not all metal ions yield flame colors. Also, some metal ions display colors that are similar to each other making it hard to tell them apart. Nevertheless, the test is still useful for identifying numerous metals and ...
( prepared hy disolving 4g of benzidine base in 10 ml of con.HCl ; and then diluting the solution to 1 litre with distilled water). Mix throughly giving a whirling motion to the beaker. Allow the beaker stand undistrubed for about 15 minutes, when all the sulphate ions will be ...
Write the net ionic equation, including phases, that corresponds to the reaction Cu(NO3)2(aq)+K2S(aq) \rightarrow CuS(s)+2KNO3(aq) Write a net ionic equation for the reaction that occurs, when aqueous solutions of hypochlorous acid and barium hydroxide are combined. ...
