Alendronate-Functionalized Poly(2-oxazoline)s with …
A library of poly(2-oxazoline)s functionalized with controllable amounts of alendronate, hydroxyl, and carboxylic acid side groups was successfully synthesized to create novel polymers with tunable affinity for calcium ions. The affinity of alendronate-containing polymers for calcium ions was quantified using isothermal titration calorimetry. Thermodynamic measurements revealed that the

Look at the compounds we tested and explain how we can be sure that it is the metal atoms that are responsible for the colours that you see. We can know for certain that it’s the metal that causes the colour because they have polar covalent bonds so the electrons are more around the metal than the non-metal so they release the colour based on the energy of the metal because that is where the

I''m studying about the s-block elements in my course of Inorganic Chemistry and I happened to come across the following text. Electrons may be quite readily excited to a higher energy level, for example in the flame test. To perform this test, a sample of Metal Chloride or any salt of metal moistened with conc. HCl, is heated on a platinum or nichrome wire in a Bunsen burner flame.

Why are chlorides used in flame test? | Socratic
2016/6/21· There are two reasons why chlorides are used in flame tests. > 1. Metal chlorides are usually more volatile than other salts. More of the salt will be converted to vapour in the flame and therefore give a brighter colour. 2. Chlorine atoms do not emit energy in the visible region. In the flame test, electrons in both the metal atoms and the chlorine atoms are excited to higher energy levels

Color of Transition Metal Complexes
Color of Transition Metal Complexes The variety of color among transition metal complexes has long fascinated the chemists. For example, aqueous solutions of [Fe(H 2O) 6] 3+ are red, [Co(H 2O) 6] 2+ are pink, [Ni(H 2O) 6] 2+ are green, [Cu(H 2O) 6] 2+ are blue and [Zn(H
