I am having a review test soon and I was not taught anything about ionic stuff last year, I have no idea what it is at all.
Sample questions look like:
"which of the following compounds are considered to be ionic solids? If it is an ioni solid, write an equation showing the dissociation of the compound as it dissolves in water"
eg. NiCl2, ClF5, NaOH
First I have no idea what an ionic solid is. why is it even dissociating when it dissolves in water. How would I know if its ionic solid or not?
I have to write an equation. Is it like decomposition, single replacement, synthesis that kind of equation? what becomes reactant or the product? I have no idea what is happening! Is part of this requiring memory work, or is it all mathematical, or do i have to refer to the periodic table, or is it logic, or do I have to think about it? I am totally lost
Also I have a question like this:
Ca(OH)2 has low solubility. write the net ionic equation for the reaction that occurs when NaOH(aq) is mixed with Ca I2 (aq) Identify the spectator ions.
I have the answer but I totally don't know how it came up. How do i know if something is positive or negative charge? What becomes solid or liquid?
If someone could clarify this all up for me, that would be really appreciated
