Octahedral Complexes Octahedral complexes are formed when a central metal atom or ion forms six coordinate bonds This could be six coordinate bonds with six small, monodentate ligands Exampl...
Monodentate ligands Monodentate ligands can form only one dative bond to the central metal ion This is because they have a single lone pair of electrons to form a dative bond with the metal ...
Coloured Ions Perception of colour Most transition metal compounds appear coloured. This is because they absorb energy corresponding to certain parts of the visible electromagnetic spectrum ...
已经下定决心做一个EPQ项目，却呆坐在一个空白的电脑屏幕前，不知从何入手... ...这是不是你？EPQ的全称是Extended Project Qualification，是A-Level课程以外的独立研究项目，涉及到大量写作、计划和自我激励。e...
Transition Metal Complexes Transition element ions can form complexes which consist of a central metal ion and ligands A ligand is a molecule or ion that forms a co-ordinate bond with a tran...
General Properties of Transition Metals Transition metals are elements with an incomplete d-subshell that can form at least one stable ion with an incomplete d-subshell This definition disti...
Redox Titration Calculations Redox Titrations In a titration, the concentration of a solution is determined by titrating with a solution of known concentration. In redox titrations, an oxidi...
Fuel Cells A fuel cell is an electrochemical cell in which a fuel donates electrons at one electrode and oxygen gains electrons at the other electrode These cells are becoming more common in...
Storage Cells Electrochemical cells can be used as a commercial source of electrical energy Cells can be described as primary, secondary or fuel cells Primary cells are non-rechargeable (irr...
