Plz explain briefly
- What will be the result (description of appearance) of Tennessine and Potassium bromide solutionWhy must solid remain in constant contact with a solution of sparingly soluble salt in order to ensure equilibrium?If a deep blue color and no precipitate are obtained when excess ammonia is added to an unknown solution for Group II, which ion/s is/are absent? Which are present? And which are indeterminate ( no sufficient information to determine their absence or presence)
- In this activity, you will develop an experimental procedure to solve a problem. Consider the followingscenario:You are the manager of a chemical stockroom, and find a bottle containing approximately one liter of aclear and colorless solution of unknown identity and concentration. Your only clue to its identity is thatit was found between bottles of silver fluoride and sodium fluoride, so it is likely an aqueous solution ofone of those two compounds. You will need to develop a procedure to determine the following:a) The identity of the unknown solutionb) The concentration of the unknown solutionWrite out a precise procedure, which includes all glassware, reagents, and steps. You will also need towrite the calculations that you would need to determine the concentration of the solution. Assume thatyou have access to any reagent you might needWhy are many ionic precipitates washed with electrolyte solution instead of pure water?When the two salts from part (g) are dissolved in water and the solutionsmixed, a green precipitate called Magnus’s green salt forms. Propose achemical formula for this salt and assign the corresponding systematic name.
