26 In order for the gravimetric analysis of MgCl2 in the simulation involving stoichiometry to be valid, all of the chloride ions must be precipitated. How can ensure this?a. Add silver ions in excessb. Have roughly, the same amount of the reactant c. Add chlorine ions in excessd. Add the same volume of reactants 27 this occurs when the energy within a phase of matter is less than the strength of the intermolecular forces:a. Solid to Gasb. Liquid to gasc. Gas to solidd. Solid to liquide. Two of the choices
If the barium sulfate precipitate is not dried thoroughly, will the experimentally determined concentration be higher or lower than the true value? Concisely explain based on how the molarity is calculated.
This is an unknown solution which comprises of several ions possible for analysis. From the given information, determine which ions are present. Use + for positive, - for negative, or ? for insufficient information. An unknown solution containing the ions listed to the right was found: For Group I Cations: 1). A white precipitate was generated when 2 drops of 6M HCl solution was added to the unknown solution test tube. 2). Di water was added to the solution from part 1, and then the ppt was separated from the supernatant. The ppt was then washed with DI water few times to make sure is ppt is clean. 3). On the ppt separated from part 2 excess 6M NH3 was added and as a result all the ppt was dissolved. For Group III Cations: 4). An addition of Excess 6M NH3 led to a basic solution and a ppt. The ppt was then separated from the supernatant. 5). When Excess 6M NaOH was…
The following glassware is used when we do titrimetric analysis.
