2
Q
what is an ionic insoluble salts also called?
A
a precipitate
3
Q
how do you choose what salts to react togehter ?
A
you pick 2 soloutions
-one that contains th enegative ions you eant
-one that contains the positvie ions you want
4
Q
what happens once the precipitatte forms?
A
we can filter the insouble salt from the soloution by wasing it and using filter paper and a funnel to dry it
