Q

Why are ionic compounds soluble in water (Eg NaCl)

A

Hydrogen = more positive
Oxygen = more negative
so the positive atoms will be attracted to the negative oxygen and the negative atoms will be attracted to the positive hydrogen
This breaks it apart as the H2O bonds are stronger

Q

How do you know how strong the bond is in ionic bonding

A

By Multiplying the ionic charges together. The higher the number the stronger the bond

16
Q

why do ionic bonds have really high melt and boil points

A

because they have a giant ionic lattice which have very strong forces of attraction

17
Q

do ionic compounds conduct electricity

A

only when molten or in an aqueous solution because then the ions are free to move

18
Q

what is the charge of Hydroxide

A

-

19
Q

what is the charge of ammonium

A

+

20
Q

what is the charge of carbonate

A

2-

21
Q

what is the charge of nitrate

A

-

22
Q

what is the charge of sulphate

A

2-

23
Q

How strong is the attraction in all ionic bonds so therefore how high or low is their melting point

A

very strong
high melting point

24
Q

how is the force of attraction (and therefore melting point) affected by the charge of ions in an ionic compound

A

-higher charges have higher melting points because the attraction between particles is even stronger

25
Q

can ionic substances conduct electricity

A

only whenliquid/dissolved because then the ions can move freely
