We are asked to complete a table, and i don't have a table, to say whether precipitate forms when solutions a and solutions b.
00:19
Okay, for my first one, empirical formula, and then i also want the formula.
00:33
Okay, first, i've got manganese 2 bromide, manganese 2 bromide, and nickel 2 acetate.
00:57
My next one, manganese, yes or no, copper two chloride and sodium hydroxide.
01:09
My next one is sodium chloride and ammonium bromide.
01:23
Let me make sure i've got all these.
01:27
So let me see again.
01:28
Mangonez two bromide, check.
01:32
Nickel two acetate, check.
01:35
Copper two chloride, check.
01:38
Sodium hydroxide, check.
01:39
Sodium chloride or ammonium bromide.
01:43
Precipitate.
01:44
This one is a definite no.
01:47
Because all the ammonia and all this, so it doesn't matter for the formula.
01:54
What else if i got? i've only got three.
02:01
So my only possible precipitate here would be my nickel 2 bromide and i'm pretty sure is n -i -b -r -2 soluble in water.
02:15
I'm sure it is...
