period 3 oxides and water Flashcards
what is the bonding in sodium and magnesium oxides
they are ionic bonding
what form of oxides are they and why
they are basic oxides as they dissolve in water to form basic soultion
why is there a difference in ph when sodium and magnesium oxides dissolve in water
nao readily dissolve wheras as magnesium oxide is less soluble
what is the role of water in these reaction
acid
why does the bonding produce basic properties
there is ionic bonding of na + to o2- the o2- react with h+ to form oh-
what does aluminium oxide act like and why
it is amphoteric ionic bonding with colvalent charecter so doesnt dissolve in water
what type of oxide is sio2
it is an acidic oxide
why does the ph remain 7
no h+ or oh - produced as macromolecular with strong covalent bonds and water cannot break these bonds
what type of oxide is p4010
it is an acidic oxide because of itds molecular sturcture
what acid does it form and with an oxidation state of what
it forms h3p04 with an oxidation state of -3
what is the ph like and why
ph is 0 as it dissociates completely in water
how does sulphur dioxide react with water
form sulforus acid h2so3
what is the ph like and why
it has a ph of 3 as it is a weak acid and only partially dissociates in water
how is h2so4 formed
when so3 reacts with water
