metal aqua ions Flashcards
what happens when metal compounds dissolve in water
the water ligands form coordinate bonds with the metal ions forming a metal aqua ion complex
what does metal aqua ion react with water to form
acidic solution of h30 which release h+ ions
what is the reaction called
a hydrolysis reaction
what happens as the metal charge increases to the ph
the ph decreases from 6-3 aciditiy increases
how do we lose the h+
the oh bond in water must break
with the electrons being pulled towards the oxygen
how does the breaking differ in different compound
when there is a smaller charge to size ratio
there is less polarising power
which means there is less weakening effect on the OH bond
What happens when metal aqua ions react with bases
react to form neutral insoluble precipitate to further react through ligand substitution
