The molecule below has been designed as a FRET-based sensor for
Lead (II) (Pb+2) cations. It contains a coumarin group that absorbs
321 nm light and emits at 385 nm. It also includes a
4-trifluoromethylaminocoumarin group that absorbs at 375 nm and
emits at 490 nm on the other end of the molecule. When running
fluorescence spectra with this compound, one peak dominates
initially, but a different peak becomes the largest after the
addition of Pb+2 salt to the solution....
Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics.
Qualitative Analysis of Metal Cations Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics. One such scheme is shown in the flow diagram. Some ions that are soluble in all of the test solutions can still be identified based on flame tests. Certain ions impart characteristic color to the flame.Part AA solution contains some or all of the ions Cu2+, Al3+, K+, Ca2+, Ba2+, Pb2+, and NH4+. The following tests were performed, in...

Nitric acid oxidizes sulfide ion to sulfur. Explain on the basis of net ionic equilibrium equations and LeChatelier's principle why CuS dissolves more readily in HNO, than in HCI. 3. means of appropriate calculations, determine whether the nickel precipitate obtained at pH 8 was Ni(OH)2 or NiS 4.

Qualitative Analysis Lab Introduction design and carry out a chemical analysis scheme to separate and identify a series of cations and anions. By this point in your chemistry career you will have encountered a fair amount of chemistry and are familiar with most of the fundamental techniques that we use in general chemistry. This lab will require two class sessions to complete. You will have the chance to apply knowledge you have gained from previous labs and learn about the...

Hi, based on the two tables shown above please answer the
following question:
1. You are given a solution that contains one of the ions Ag+
, Pb+2 or Ba+2 . Based on your
observations in this experiment, develop a procedure to
determine which ion is present.
More than one reaction may be required to discover the ion’s
identity. Explain how your
procedure will determine the identity of the ion.
