Chemistry Flashcards
Ionic structure is?
Giant lattice of alternating positive and negative ions
Why can ions conduct electricity when molten/dissovled?
Because the ions are free to move
rememebr the practical
Does an ion compound have a low or high melting point
High melting point
souble means able to be dissolved
Is an ionic compound soluble
Yes
Does an ionic compound conduct electricity
No
it can only conduct electricty when its a molten/ liquid
Can ionic compounds dissolve in water
Yes
What would potassuim fluorine be called
Potassuim floride
What would calcium and fluorine be called
Calcium floride
What would Aluminuim sulfur be called
Aluminium sulfide
How would a solid look like or be described
Stuck together in rows/vibrate/can conduct electricity
What would a liquid look like or be described
Stuck together not in rows/ vibrate/can conduct electricity
Descrbe the structure of an ionic compound
An ionic compound is a giant lattice held together by the electrostatic attractions between oppositely charger positive and negative ions
Why do ionic compounds have a high melting point
To melt an ionic compound all the ionic bonds need to be brokers and there is a large amount of energy that would be used to break the bonds lots of heat is needed
Explain ionic compounds can conduct electricity when dissolved in water but not when it’s a solid
Because the ions are not free to move in a solid so when it’s liquid the ionic lattice I’d broken down allowing the ions to move freely
