now cops is used for insoluble ionic salutes. And we're gonna say it also has its exceptions. Now these exceptions will now create soluble a quiz ionic compounds. So we know that cyber acquis ionic compounds will break up into ions. Now how do we remember the exceptions here? We're just gonna say oh snap, it's the cops. So when we're looking at the term cops, exceptions can arise when we get to oh and when we get to s so here if we take a look here at this chart we have C C. Here represents carbonate ion and also chrome eight ion. So carbonate and chrome eight if we're just looking at cops and not thinking about uh Ghana Cash, we're gonna say there are no exceptions. So we're gonna form a precipitate in this case stands for oxides which is 02 - and hydroxide which is O H minus. Now here this is when we have our exceptions. So here the exception is something we remember cbs when we talked about johnny cash. Now here this means that if oxide or hydroxide are connected to calcium, barium or strontium, they're gonna create a soluble acquis compound which can break up into ions. Next we have P which stands for phosphate. Remember phosphate ion is p. 0. 4 3 here, we're just looking at cops itself, we have no exceptions. It'll fall and precipitate. And then finally we have S which stands for sulfide Which is S 2 -. It also has the same exceptions as Oh so here calcium, barium and strontium. So keep this in mind, we're gonna use a we're gonna look at Ghana cash and cops overall to tell if a compound at the end of the day is soluble or insoluble.
